Unit 1.2 Physics

Displacement

The displacement of a point B from a point A is the shortest distance from A to B, together with the direction

1 of 8

Mean speed

Mean speed= total distance travelled/total time taken (Units: m/s)

2 of 8

Instantaneous speed

Instantaneous speed= rate of change of distance (Unit: m/s)

3 of 8

Mean velocity

Mean velocity= total displacement/total time taken (Unit: m/s)

4 of 8

Instantaneous velocity

The velocity of a body is the rate of change of displacement (Unit: m/s)

5 of 8

Mean acceleration

Mean acceleration= change in velocity/time taken (Unit: m/s^2)

6 of 8

Instantaneous acceleration

The rate of change of velocity (m/s^2)

7 of 8

Terminal velocity

The constant, maximum velocity of an object when resistive forces on it are equal and opposite to the accelerating force (gravity)
