| Question | Answer |
| What are scalers? | Quantities that have magnitude only |
| What are vectors? | Quantities that have magnitude and an associated direction |
| Give an examples of scalers | Speed Time |
| Give examples of vectors | Displacement Velocity Acceleration Force Momentum |
| What does a distance time-graph represent? | How far an object is from a certain point if it moves in a straight line |
| How can the speed of an object be determined from a distance-time graph? | The gradient |
| If an object is accelerating, how can its speed at any given time be determined from the distance-time graph? | By finding the gradient of the tangent of the graph at that time |
| What is velocity? | The speed of an object in a given direction |
| How can you determine the acceleration of an object from a velocity-time graph? | The gradient |
| How can the distance travelled by an object be determined from a velocity-time graph? | The area under the graph |
