Prove how Newtons laws of motion apply to the physical world...
I will prove it by doing multiple experiments like proving inertia showing how friction and gravity apply to newtons laws,and the relation between speed and acceleration, i have done real life siuations that prove how Newtons laws of motion
&&&&How friction and gravity apply to newtons laws...
*i will drag a car over 3 different types of surfaces and rate them using a scale of 1-10 ( 1 being very difficult to move on surface and 10 being very smooth and easy to move)
hypothesis: i am using 1 toy car on 3 different surfaces ( plastic, wood, and a plastic track designed for cars) so that i can show how friction can affect say the speed of a car. i think that the plastic track that is made for cars will be the smoothest because that is what it is made for.
material 1 toy car, a plastic track, a flat piece of wood, and 1 smooth plastic board
veriables
mv: surface
cv: the car, the angle, the judge and the amount of force used to move the car
rv: what surface is better
procedure
gather all materials
place car on wood track
put the track at a 90degree angle
let go
record results
place car on plastic track
put track at a 90 degree angle
let go
record results
place car on smooth piece of plastic
put track at a 90 degree angle
let go
record results
repeat these steps at 2 other angles (45 & 60)
graph results
conclusion
clean up
Conclusion: I had predicted in my hypothesis that the plastic ramp that was made for cars was going to be the smoothest due to the fact that they are designed for it and i was correct because as my results said it went significantly faster and smoother on the ramp then any other of the 3 surfaces because it had less friction so it didnt slow the car down.
____also i had both cars drop from the same height and record the time taken or each one to fall car A was light and car B was heavy.
hypothesis's: i think car B will fall faster then car A because it is much heavier then car A so gravity will pull it down faster also it has to do with the mass of the car.
materials
2 cars one is heaver, stop watch, and a solid surface
variables
cv- the height
mv is the car
rv- witch one takes a shorter time to drop
conclusion the car with the greatest mass fell faster then the one with less mass this due to the fact that gravity is pulling the car with higher mass more than the one with less, my hypothesis was correct.
@@@The relationship between speed and acceleration...
i will do a inertia problem where i will have a small car go down a ramp and hit a large car and vice versa then record the results of how far each car pushes the other one.
hypothesis:the bigger car will push the smaller car further event though it will have less speed and less acceleration it will have more force to push the car.
materials 2 cars, 1 ramp, and 1 ruler
mv- location of car
cv- where ruler is, angle of ramp, the two types of car
rv- which car pushes the other one further
procedure
gather all materials
place car 1 on the ramp
place car b at the end of the ramp
place a ruler next to the end of the ramp
let car a go
recorde how far back car b was pushed
repeat 2-3 time more
do this for car b as well
****How simple machines utilize the mechanical advantage to transfer energy...
+I will create a Rube Goldberg to show how you can transfer energy with say a bump
There is a bowling ball that is pushed with a mouse trap and then that bowling ball is rolling on ground level then it bump's into another bowling balls that bowling ball that was standing still is now moving because of the energy transferred by that bump
$$$$Effectively explain how alternative forms of energy ca be utilized to influence the United States needs...
