Ques+ Practice - Forces and Motion

A motorbike moves along a road at 25m/s.

Calculate the distance moved in 50s.

• 2 m

• 0.5 m

• 125 m

• 1.25 km

A motorbike moves along a road at 25m/s.

Calculate the time taken to travel 2 kilometres.

• 4 s

• 80 s

• 0.08 s

• 40 s

Which of these is the correct formula for acceleration?

• change in velocity x time taken

• change in velocity ÷ time taken

• velocity x time taken

• velocity ÷ time taken

A train accelerates from 10 m/s to 50 m/s in 20 seconds. The acceleration is:

• 2 m/s²

• 2.5 m/s²

• 800 m/s²

• 1000 m/s²

If a car accelerates at - 3 m/s², what does this mean?

• It is moving backwards at a constant speed

• It is slowing down

• It is accelerating but 3 m/s² less than before

• It is accelerating forwards, but the resultant force is backwards

Which of these 4 distance (s) -time (t) graphs shows a car accelerating?

• A

• B

• C

• D

This velocity-time graph shows the journey of a bus as it moves away from a road junction.

 

What quantity is shown by the gradient of line A?

• acceleration

• distance travelled

• change in velocity

• average velocity

This velocity-time graph shows the journey of a bus as it moves away from a road junction.

 

What quantity is shown by Line B?

• acceleration

• distance travelled

• change in velocity

• maximum velocity

This velocity-time graph shows the journey of a bus as it moves away from a road junction.

 

What quantity is shown by the area under the line?

• acceleration

• distance travelled

• change in velocity

• maximum velocity

This velocity-time graph shows the journey of a bus as it moves away from a road junction.

 

What quantity is shown by the gradient of line C?

• acceleration

• deceleration

• change in velocity

• average velocity
