Question | Answer |
---|---|
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* |
