5. Displacement The distance an object has travelled in a given
direction

6. Velocity Rate of change of displacement

7. Acceleration Rate of change of velocity

8. Scalars mass, time, temperature, speed, energy

9. Vectors displacement, force, velocity, acceleration

10. Velocity= u + at

11. Acceleration Change in velocity divided by time

12. Displacement= Average velocity × Time

13. Displacement= ut + ½at²

14. Velocity²= u² + 2as
