Newton Laws Assessment

1. What are the relationships between forces and motion? 
The relationship between forces and motion is that force creates movement. Force is like when something is pushed and when something is pushed with a good amount of force then it will move. Like if there is a tennis ball on the ground, and you kick it, then it will move. The force from your foot hitting the ball made it roll away from you. 2. What are the variables that affect motion and force? 
A variable that affect motion and force can be either on earth or in space. On earth if you push something, it will eventually stop due to friction and object that lie on earth. In space, if you push something than it will keep going. It may bounce off things but it will keep going. 3. How does Newton’s three laws describe the motion of a moving 
object? 
The first law says that when a object is put into motion then it will tend to stay in motion. That says that when something is put into motion then it will stay in motion. The second law describes motion with net force and mass of an object which effects how far an object can move. Newtons third law describes the reaction from the main reaction. So the after effect. 4. How does gravity impact objects?
Gravity can cause friction which can cause something to slow down over time, but if there is no gravity, then it will keep going. It may hit other objects but it will stay in motion because it will bounce off other objects. With gravity, an object will eventually stop and become still until it is pushed again.

Metal car lab

In Physical science this week we did a lab that has to do with force, acceleration, and mass. We were given a metal car and a set of weights spanning from 5g to 1000g. We then set up a wood runway for the metal care to go down. Each time we made the metal car go down the ramp, we would time it, and each time we would put a heavier weight. We used a back pack to make the slope a slant and we used a binder to make the car stop. I really enjoyed this lab, I think it was a fun way to see how weight may affect a car on a hill and it gives me a better understanding of what weight really does.
