| What is a resultant force? | A single force that has the same effect on the motion as the original forces all acting together |
| If the resultant force acting on a stationary object is zero, what will happen? | The object will remain stationary |
| If the resultant force acting on a stationary object is not zero, what will happen? | The object will accelerate in the direction of the resultant force |
| If the resultant force acting on a moving object is zero, what will happen? | The object will continue at the same speed in the same direction |
| If the resultant force acting on a moving object is not zero, what will happen? | The object will accelerate in the direction of the resultant force |
| What is the conservation of momentum? | The idea that the total momentum before an event is equal to the total momentum after the event |
