First Experiment Force and Newton’s laws :Marble and golf ball and Dominoes
Problem- Which will have more force on the dominoes, is it the golf ball, that has more mass or is it the clear marble that has more speed. Does speed affect the force?
Hypothesis- I think that if I used the golf ball than it will have more force on the dominoes than the clear marble because, the golf ball has more mass than the clear marble. Even though I think that the golf ball marble will have more force because it has more mass and also because it is bigger. It doesn't mean that the clear marble can't knock over the dominoes just because of it's mass. The clear marble could possible knock over the dominoes because of its speed but I just think that if you have a higher mass than you will have a better chance of knocking over the dominoes. Does speed affect the force? I think that speed can affect the force because if the marble is going really fast then it could possible nock over the Dominoes causing a force.
How Newton's laws apply in my experiment and in the physical world?
Newton's laws apply in my experiment in all different kinds of ways. Newton's first law is; an object at rest will remain at rest and that object that is at rest is the Dominoes because they are not moving. The seconded half of Newton's first law is; an object in motion will remain in motion in the same direction unbalanced force acts upon it, and the object that is remaining in motion in the same direction is the two different type of marbles. The unbalanced force is the dominoes because they are getting knocked over. Now that the first law is done we can move on to Newton's seconded Law. Part of Newton's seconded law is; the relationship between force and acceleration. The force is the marble knocking over the Dominoes. The acceleration is just the marble because when it is going down the track builds up more speed and therefore it can knock over the dominoes. The seconded part of Newton's seconded law is; greater the force, the greater the acceleration. That just means the more force the marble has the faster it will go.
Materials-
One clear marble that is normal size
One golf ball
10 dominoes
Wooden track
Clean Space
Ruler
Procedure
1. Gather all materials.
2. Then set up project.
3. Put the wooden track down on the table first.
4. After when you’re done with that measure 1 inch on your ruler away from the wooden track then put down the first domino.
5. Then fowl with the other 9 dominoes but make sure this time you measure 1 centimeter apart from each one.
6. Then when you are all done setting that up take your clear marble and roll it down the track and see how many dominos it will nocks over
7. Make sure when you are doing this write how many domino fell every time
8. When you’re done with that do you project all over again but this time do it 5 times and see if it changes anything.
9. After when you’re done with that, set up you new experiment for this project
10. Put the wooden track down on the table first.
11. After when you’re done with measuring 1 inch on your ruler away from the wooden track, put down the first domino.
12. Then fowl with the other 9 dominoes make sure you measure 1 centimeter apart from each one like you did with the marble
13. Then when you are all done setting that up take your golf ball and roll it down the track and see how many dominos it will nocks over
14. Do that all over again 5 times
15. Then see which one has more force and does speed really effect the force
Identifying Variables
CV- same track, same height for the track and width, same dominoes, same golf ball, same marble, and same setup
DV- The force
IV-The weight of the golf ball and marble
Control- The kind of marble
What are my results?
My results show that the golf ball has more force than the marble. Even though I thought that if there was more speed it could possibly nock it over some dominoes but I was wrong with that.
Data table
Golf ball Marble
ALL none
ALL first one moved a little but did not knock over any
ALL none
ALL first one moved a little but did not knock over any
ALL none
ALL none
Observation
I saw that the golf ball was way more powerful than the marble because of its mass, the golf ball has a lot more mass then the marble because the marble is much smaller.
My hypothesis was?
My hypothesis was right because I knew that if there was more mass than it would have been an easier chance of knocking over the dominoes and also I was write because speed does effect the force. It affects the force because it shows that if it's going really fast it can give off a lot of power.

Friction and Gravity
Third Experiment Hula hoop
Friction and gravity apply to my experiment by, while hula hooping and stopping my body I am the unbalance force that acts upon the hula hoop making the hula hoop move downward towards the ground because of gravity.
Problem-If I am hula hooping for one minute long the same paste and I all of sudden I stop would it take longer than 3.3 seconded to the gowned?
Hypothesis-In my option I think that if I stopped automatically then I think that it will take 3.5 sec to reach the grown because of gravity, It will bring the hula hoop down.
Newton's laws
Newton's first law an object at rest will remain at rest. Then object that is remaining at rest is the hula hoop because once it hits the floor it will need someone to pick it up because the object will not move unless someone moves it. The seconded part of Newton's first law is a object in motion will remain in motion same direction unbalanced force acts upon it. The object that is in motion is, myself because I am moving my hips. I have to move my hips because if I don’t then the hula hoop will just drop to the floor. Newton's seconded law; greater the force, the greater the acceleration. That means the more force I put on the hula hoop the faster the hula hoop will go.
Materials
Myself
2 Timer
Hula hoop
And another person to time
Procedure
1. Gather all materials.
2. Make sure you have two timers in your hands.
3. Take the first time watch and once you start hula hooping start the timer.
4. When it close to one minute give the person a 10 seconded warning and get ready to start once it hits a minute .
5. When the whole minute is up stop with the timer and make sure the person that are timing does not move then start with new timer when they are done hula hooping
6. Make sure to recorded your timings
7. Now that was the first one now all you have to do is make sure you have two timers in your hands.
8. Take the first time watch and once you start hula hooping start the timer.
9. When it close to one minute give the person a 10 seconded warning and get ready to start once it hits a minute .
10. When the whole minute is up stop with the timer and make sure the person that are timing does not move then start with new timer when they are done hula hooping
11. Now you have two tests done and you just have to do one more tests and that is exactly what we did up there
12. Make sure you have two timers in your hands.
13. Take the first time watch and once you start hula hooping start the timer.
14. When it close to one minute give the person a 10 seconded warning and get ready to start once it hits a minute .
15. When the whole minute is up stop with the timer and make sure the person that are timing does not move then start with new timer when they are done hula hooping and now you are all done with you test!

My results
My result showed that gravity will take over because, well it is the earth and is shows that there is gravity on the earth. If we didn't have gravity in life then there would be a lot of conflicts in the world trying to get to place to place.
Observations
I saw that while I was doing my experiment that the gravity will always pull down toward the ground usually, never up. Also I have notice that it takes a shorter amount of time to hit the floor than I thought.
My hypothesis
My hypothesis was wrong and right because it actually took a shorter amount of time than 3.3 seconds. I was right about gravity will bring the hula hoop go down because if we didn't have gravity on this earth then there would be no way of getting basket balls, baseballs, tennis balls, soccer balls edc., out of the sky. So that’s good if we have gravity.

Speed and aceleration
Fourth Experiment Speed and acceleration Fan
Speed and acceleration apply to my experiment by, if you are turning on or off a fast it starts of slow and it gets faster and faster, same with when you are turning off a fan it starts off slow when you are turning it off and it eventually will get slower and then turn off.
Problem-If I turn on a fan and leave it on for one minute and thirty second how much time will it take to be completely off?
Hypothesis- I think that it will take about 3.5 seconds to turn completely off because it takes time for the fan to turn completely off because of its acceleration.
Materials
Fan
Two Timer
One person
Outlet
Clear and clean space
Procedure
1. Gather all materials
2. Make sure that you have a clean and clear space to therefore it will be easier to work
3. Make sure that you have a timer in your hand
4. Plug in your fan start the timer as soon as you turn on the fan
5. And when it gets close to one minute and thirty seconds put down the timer and grab a the new timer/ but make sure you do not turn off the other timer.
6. Write when it hit 1:30 on the timer turn off the fan write away make sure when you’re turning off the fan you start the timer as soon as you do that.
7. See how long it takes for the fan to turn completely off when your timer has stopped
8. Record you score on a separate sheet of paper or on your laptop
9. Repeat all steps over again four more times so therefore you have done this experiment five times in total
Variables
CV- same person that is timing, same fan, same timers, and same outlets
IV- the acceleration
DV- the speed/fan
Control- type of fan
My results
My results showed that my experiment can work because the acceleration on the fan is slowing down and not speeding up.

Observations
In this trail I saw it took a lot shorter time then I expected. I only took 2.3 then what I thought which was 3.5 seconds.
Hypothesis
My hypothesis was wrong because I thought that it would take a lot longer slowing down. It still took awhile to slow down but not as long as I thought it was it took about 2.3 seconds to be completely shut off. I thought that it would take at least 3.5seconds to shut of I was off by a whole seconded. Otherwise I had whole experiment write if I would got guessed the timing but I was kind of close to what is was actually but not exact.

Solar Energy
Do you know that using solar energy could be saving the world thousands of dollars? Sun light is the best natural resource that is converted into electricity. Rather than using expensive natural gas, oil, coal or wood for meeting energy requirements, you can save on a huge amount of money just by using solar energy. Solar energy can be used for industrial production such as, material testing, smelting, to heat up water/boil, cooking food, and disinfecting water so therefore you can drink health water, and much more. Solar energy is a lot more healthier for our environment because just using solar panels helps us not pollute the air. It also prevents globe warming because it doesn’t produce greenhouse effect/ which is a major cause of globe warming. The sun shines bright every morning, so why not use solar energy/solar panels; you just have to make sure that your solar energy system is working so it can run your whole household. It would control your whole household. You would need about 590 watt so it can control your stove/oven, heat, oil, refrigerator, or T.V or computer and each watt cost about $1.75 so you would just have to do $1.75 times 590 and you get $1,032.50. Well $1,032.50 might seem like a lot of money but if you realize it, it’s taking care of your whole house and plus the solar panels last about 25 years and that’s a long time think about just how much money you would be saving. If the whole planet used solar energy, the plant would be saving so much money. If we all just thought about having solar panels and actually getting them, then we would realize that getting solar panels is helping out our planet a lot. I believe that we should use solar panels because it would save us a lot more money and help out our planet a lot and preventing global warming and pollution in the air.

Rube Goldber
My Rube Goldberg starts out with the screw hanging by a pulley. The Pulley has a wheel and Axel. A marble falls down the screw, down the inclined plane. It knocks over 10 dominoes. The last domino pushes over the egg off the edge of the table and into a bowl but the bowl is balancing on a popsicle stick so therefore it is a titer totter and that bowl is attached to a string and we actually use two pulleys so once the egg drops in to the bowl the egg will crack making sure that the bowl slides off and dumps over the egg but we didn’t want the bowl to just fall anywhere so that’s why we attached it to a sting which the string is attach to the pulley. So the egg will drop into strainer that is handmade and what is under the strainer is another bowl so now you can just take the bowl that has the egg in it.
