Rate of change of position (displacement) is known as:

• acceleration

• velocity

• Force

• speed

Rate of change of velocity is known as:

• acceleration

• velocity

• Force

• speed

Final velocity is 5m/s, initial velocity is 1m/s, time taken for change is 2 seconds. Calculate the acceleration, with correct units

• 1m/s

• 2m/s

• 1m/s²

• 2m/s²

The average speed of an object is:

• total distance divided by total time taken

• total distance/2 multiplied by time taken

• total distance multiplied by total time taken

• total distance/2 divided by time taken

In a distance-time graph, the slope gives the

• distance travelled

• the time taken

• the velocity (speed)

• the acceleration

In a velocity-time graph, the slope gives the

• distance travelled

• the time taken

• the velocity (speed)

• the acceleration

In a velocity-time graph, the area under the graph line gives the:

• distance travelled

• the time taken

• the velocity (speed)

• the acceleration

Acceleration is calculated using the following formula:

• a = (u - v) / t

• a = t / ( v- u)

• a = t (u - v) / t

• a = (v - u) / t

A car accelerates from rest to 10m/s and takes 4 seconds to do so. The distance travelled is:

• 40m

• 20m

• 20 m/s

• 2.5m

The unit of Frce is the

• Newton

• Pascal

• Joule

• Watt
