Try a question

From “Describing motion”.

Questions are in English, like the exam. Every answer comes with an explanation.

What does the gradient of a displacement–time graph give?

  1. AForce
  2. BVelocity
  3. CAcceleration
  4. DDistance
Show the answer

B. Velocity

Change in displacement ÷ change in time = velocity.
