What is the distance, time and speed relationship?

Distance = time x speed

1

Distance time graph characteristics

Stationary- horizontal line
Constant speed- a straight line which slopes upwards
Gradient- shows object's speed

2

What is velocity?

Velocity is speed in a given direction.

3

What is acceleration?

Acceleration is the change of velocity per second. The unit is m/s^2

4

How do you work out the acceleration?

Acceleration = change of velocity / time taken.

5

What is deceleration?

Deceleration is the change of velocity per second when an object SLOWS down.

6

Characteristics of a velocity time graph

Horizontal line- acceleration is zero ( either constant speed or stationary)
Gradient- acceleration
Area under the line- distance travelled
