OUTCOME
By the end of the lesson you will investigate the different ways we can analyse displacement data to find the acceleration
Engage
The instantaneous speed, average acceleration and displacement can all be found from the velocity time graph
Acceleration can be found using the gradient of the velocity time graph and by numerical calculations of changes in speed over time
LEARNING TASKS
Explain
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?
Explain what the difference between acceleration and deceleration is
Explain the difference between negative acceleration and deceleration
