Graph Interpretation Lab
This shared simulation is used here to practise slope, area, and graph-shape interpretation.
Concept Capsule
- A position-time graph shows how position changes with time.
- Slope of a position-time graph gives velocity.
- A straight sloping position-time graph indicates uniform velocity.
- A curved position-time graph indicates changing velocity.
- A velocity-time graph shows how velocity changes with time.
- Slope of a velocity-time graph gives acceleration.
- Area under a velocity-time graph gives displacement.
- A horizontal velocity-time graph indicates uniform velocity.
- A sloping velocity-time graph indicates uniform acceleration or retardation.
- KCET graph questions often test slope, area and sign.
Common KCET Traps
- Confusing slope with area.
- Using area under position-time graph as displacement.
- Ignoring the sign of velocity or acceleration.
- Forgetting the factor 1/2 while calculating triangular area.
- Treating every straight line graph as acceleration.
