| Question | Answer |
| What does an object need to start moving? | A force |
| What happens when the resultant force on an object remains zero? | The object will remain stationary |
| What does 'no change in Velocity' mean? | That there is no resultant force |
| What happens if there is no resultant force on a moving object? | It'll carry on moving at the same velocity |
| What are the criteria for an object to move at a constant velocity? | All forces on the object must be balanced |
| What must an object have to keep it moving at a steady speed? | Zero resultant forces |
| What happens when there is a non-zero resultant force on a moving object? | It will accelerate in the direction of the least amount of force |
| What will a non-zero resultant force always produce? | Acceleration (or deceleration) |
| List five different forms of acceleration. | 1) Starting 2) Stopping 3) Speeding up 4) Slowing down 5) Change in direction |
