1. be apply the following
equation to situations where an average speed is involved:

2. Be able to distinguish between average speed and instantaneous speed (in effect, an
average over a short time interval) for examples of motion where speed is
changing

3. HT only: understand that the displacement of an object at a given moment is
its net distance from its starting point together with an indication of
direction

4. Be able to draw and interpret a distancetime (or displacementtime) graph for
an object that is:

5. Be able to interpret a steeper gradient of a
distancetime graph as a higher speed

6. HT only: Be able to calculate a speed from the gradient of
a straight section of a distancetime graph

7. Be able to draw and interpret a speedtime
graph for an object that is:

8. understand that in many
everyday situations, acceleration is used to mean the change in speed of an
object in a given time interval

9. know that the instantaneous velocity of an
object is its instantaneous speed together with an indication of the direction

10. HT only: understand that the velocity of an object moving in a straight line is
positive if it is moving in one direction and negative if it is moving in the
opposite direction

11. HT only: Be able to draw and interpret a velocitytime graph for an object
that is:

12. HT only: Be able to calculate the
acceleration from the gradient of a velocity–time graph (or from a speed time
graph in situations where direction of motion is constant)

13. Be able to calculate
acceleration using the equation:
