KEY KNOWLEDGE
graphically analyse non-uniform motion in a straight line
OUTCOME
By the end of this lesson you will be able to analysis and read velocity time graphs to describe an objects motion.
The instantaneous speed, average acceleration and displacement can all be found from the velocity time graph
1. What does a flat line on the velocity time graph indicate?
2. What does a negative gradient on the velocity time graph mean?
3. How do you work out the displacement of the object?
