LIST OF PHYSICS LABELLED DIAGRAMS REQUIRED FOR SCHOOL CERTIFICATE

Students are expected to draw and label these over and over again till they can memorise them:

1. Distance-time graphs of an object which is at rest, moving with constant speed, accelerating, decelerating.

2. Speed-time graphs of an object which is at rest, moving with constant speed, moving with constant acceleration, moving with changing acceleration.

3. Diagram showing how an object reaches terminal velocity.

4. Velocity-time graph showing thinking time, braking time, thinking distance and braking distance.

5. The simple barometer.
