CAIE IGCSE Physics 1.2.10 From Given Data or the Shape of a Questions

Practise interpreting acceleration from speed-time graph gradients, including constant, increasing, decreasing and non-constant acceleration in Cambridge IGCSE Physics problems.

Exam points

Interpret acceleration from the gradient of speed-time graphs, including constant, increasing, decreasing and non-constant acceleration.

[Maximum number: 3]

Fig. 1.2 shows a vertical speed-time graph for a parachutist who jumps from a stationary hot-air balloon.

Fig. 1.2

The parachutist jumps from the balloon at time =0 and reaches the ground at B. The point A indicates when the parachute opens.

On Fig. 1.2, label a point on the graph where the acceleration is:
- zero with ' 1 '
- negative with ' 2 '
- decreasing with ' 3 '.
