The mousetrap car relates to Newton's first law because the car does not move until the force of the mousetrap moves it and then it doesn't stop until it hits something or until gravity finally stops it.
 
- Newton's second law: Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Newton's second law of motion will affect our mousetrap car because the more the car weighs the slower it goes. But the less the car weighs the faster it will go because it has less mass so it doesn't take a big amount of force to move it.
 
- Newton's third law: For every action there is an equal and opposite reaction.
Newton's third law affects the car because for every action there is an equal and opposite reaction. That means that as the car is rolling that friction is pushing against it with not as much force so the car still moves. But as the car keeps going the forces equal out and the car slows down until it finally stops.

The longer the impulse or the longer the lever on the mousetrap hits the lever of the car the further the mouse trap car will go.]]> 2016-11-22 01:09:49 UTC https://padlet.com/120492/xwayhn93x73q/wish/139241570 120492 https://padlet.com/120492/xwayhn93x73q/wish/139338546 2016-11-22 13:31:51 UTC https://padlet.com/120492/xwayhn93x73q/wish/139338546 120492 https://padlet.com/120492/xwayhn93x73q/wish/139499494 2016-11-23 02:05:29 UTC https://padlet.com/120492/xwayhn93x73q/wish/139499494 120492 https://padlet.com/120492/xwayhn93x73q/wish/139609502 Mousetrap Car Calculations 

a) the initial velocity of your car.   -  0 m/s
              b) the average velocity of your car.  -  0.376 m/s
              c) the initial acceleration of the car  -  0.9891 m/s
              d) the deceleration of your car.  -  0.1196 m/s
              e) the force of friction acting on your car. - mass x acceleration 
                            289g x 0.9891 m/s = 285.85
              f)  impulse on the car - mass times change in velocity 
                            289g x 0.529 = 152.881
