| Question | Answer |
| What is the difference between Speed and Velocity | Velocity is Speed with a given direction |
| Distance time Graph What does a straight line that goes diagonally up represent | Steady Speed |
| Distance time Graph Flat line | Stopped |
| Distance time Graph Curved upwards | Acceleration |
| Curved downwards | Deceleration |
| Distance time Graph Straight line going diagonally down | Steadily moving in the other direction (backwards) |
| Distance time Graph what is the Gradient | Speed |
| What is Acceleration | How quickly velocity is changing |
| ? = Change in velocity/Time taken Change in velocity/? x Time taken | Acceleration |
| Velocity Time Graphs straight diagonal upwards line | Acceleration |
| Velocity Time Graphs flat line | Steady speed |
| Velocity Time Graphs curved line upwards | increasing acceleration |
| Velocity Time Graphs curved downwards | decreasing acceleration |
| Velocity Time Graphs downwards straight diagonal line | Deceleration |
| Velocity Time Graphs how do you calculate acceleration | Acceleration = gradient = vertical charge/horizontal charge |
| true or false everything accelerates towards the ground at the same speed | true |
| what is mass | the density |
| what is weight | weight is the gravitational force acting upon on object |
| how do you calculate weight | weight = mass x gravitational field strength w = m x g |
| What is Resultant Force | Resultant is the over all force in a direction as there is always an opposing force to every movement (?) It determines the Acceleration |
| How do you calculate Resultants Force | Resultant Force = Mass x Acceleration F = m x a |
| What happens if the Resultant Force = 0 | There is no change in velocity (A constant speed) |
