1.3 Representing Motion
Notes
- Position-time graph: slope = velocity.
- Velocity-time graph: slope = acceleration; area = displacement.
- Acceleration-time graph: area = change in velocity.
Practice
The slope of a position-time graph gives:
Change in position over time.
A velocity-time graph is a horizontal line at 4 m/s for 5 s. The displacement:
Area $=4\times5$.
A straight, sloped line on a velocity-time graph means:
Constant slope.
