linear motion

What quantity is represented by the area under a velocity-time graph?

• Acceleration

• Displacement

• Velocity

• Force
  

What does the gradient of a displacement-time graph represent?

• Distance

• Acceleration

• Velocity

• Time

Which of the following statements about a straight horizontal line on a velocity-time graph is correct?

• The object is accelerating

• The object is at rest

• The object is moving with constant velocity

• The object is decelerating

A velocity-time graph shows a straight line sloping downward. What does this indicate about the motion?

• Constant speed
  

• Increasing velocity

• Zero velocity

• Constant deceleration

What does the gradient of a velocity-time graph represent?

• Velocity

• Displacement

• Acceleration

• Force

How do you calculate average speed?

• Total time ÷ Total distance

• Total displacement ÷ Total time

• Final velocity − Initial velocity

• Total distance ÷ Total time

What is the correct formula for displacement when initial velocity, time and acceleration are known?

• s=ut

• s=ut+1/2at²

• s=vt−1/2at²

• s=v²−u²
