A measure of how far an object has travelled

• speed

• distance

• time

• velocity

A measure of how long an object has been travelling for, measured in s

• time

• speed

• distance

• acceleration

A measure of the rate of motion of an object

• speed

• acceleration

• time

• deceleration

The rate of change of speed per time

• velocity

• speed

• time

• acceleration

Negative acceleration

• speeding up

• constant speed

• deceleration

• at rest / stopped

In a distance-time graph, the gradient of a sloping straight line shows

• object has stopped

• object is at constant speed

• object is accelerating

• object is returning to start position

In a distance-time graph, a horiziontal straight line shows

• object has stopped

• object is at constant speed

• object is accelerating

• object is returning to start position

In a distance-time graph, a curved line that is getting steeper and steeper shows

• object is decelerating

• object is at constant speed

• object is accelerating

• object is returning to start position
