QuestionAnswer
Momentum A measure of an object’s motion and how likely it will remain in motion
Force Any push or pull
Braking Brakes apply a force that stops vehicles by decreasing their momentum
Friction This is the force between two objects exert on each other when they press against each other
Impulse The combination of the size of force and the time it takes. This equals a change in momentum or an impulse.
Law of conservation of momentum During a collision one vehicle will lose momentum and at the same rate one will gain it. *The total momentum of two colliding objects stays the same after their collisions*
