Average speed can be calculated from the distance travelled and the time taken. The gradient of a distance-time graph is equal to the speed. Relative motion takes into account speed and direction.

What is the correct equation for calculating speed?

Distance multiplied by time

Time divided by distance

Distance divided by time

What are the correct units for speed?

Miles per hour

Metres per second

Kilometres per hour

What is the correct equation for calculating time?

Distance subtracted from speed

Distance multiplied by speed

Distance divided by speed

What is the correct equation for calculating distance?

Speed multiplied by time

Speed divided by time

Time divided by speed

What does a horizontal line in a distance-time graph show?

Fast moving

Slow moving

Stationary

What does a steep line in a distance-time graph show?

What does a gently sloping line in a distance-time graph show?

What goes on the x-axis in a distance-time graph?

Distance

Time

Speed

How do you calculate the relative speed of objects moving in the same direction?

Fastest speed minus slowest speed

Slowest speed minus fastest speed

Slowest speed multiplied by fastest speed

How do you calculate the relative speed of objects moving in the opposite direction?

Add both speeds together

Multiply both speeds together
