Title: May The Force Be With You
Abstract:
Experimental Question: How does the mass of the first model source car affect the acceleration of the second model source car at rest to in motion?
Research: When we drive our cars, motorcycles, trucks, or any vehicle down the road, we are driving them at a certain velocity and direction. All vehicles have a mass to the order of a few hundred pounds. When our vehicles move at a certain speed down the road, they create an energy by the property of their mass and forward velocity. This energy is called Kinetic Energy. Assuming the mass of a vehicle is assumed to be constant, it will create a certain quantity of kinetic energy while in motion at speed.

I think that if the first car has a heavier mass it will make the second car accelerate slower because if the first car is heavier then it adds mass and will slow down so the force hitting the second car won’t be as strong so the acceleration will be slower. So if the first car's mass is lighter than the second car will accelerate faster.
Analyze Results: I reject my hypothesis that if the first car has less mass then the second car will have a greater acceleration. My data shows that as the first car gains mass the second car will accelerate more, for example: when the mass of the first car is at 0 grams it accelerates at about 0.66 m/sec and when the mass of second car is 240 grams the acceleration increases to about 0.73 m/sec. But when the mass of the first car was 480 grams the acceleration was constant at 0.73 m/sec, then when the mass was increased at its heaviest with 720 grams, the acceleration decreased to 0.64 m/sec and the 240 and 480 gram trials stayed consistent.

Force = mass x acceleration. So since when the first car was heavier it made the acceleration of the second car increase. With heavier mass makes a stronger force which then transfers into a greater acceleration. This shows that with greater mass makes greater force which then makes greater acceleration so that might be why when the mass of the first car was more we had a greater acceleration.
The conservation of momentum can be a huge effect on the cars, so the conservation of momentum states that when there are no other outside forces like friction the total momentum of the objects interaction does not change. The amount of momentum before and after the collision will be the same. If this is the case then the momentum of the first car, mass times velocity, does not change the momentum of the second car if the second car is at rest so the second car would have the same momentum as the first
