Consider the acceleration, velocity and displacement of a tennis ball as its falls to the ground and bounces back. Directions of which of these change in the process?

Options

  1. AVelocity only
  2. BDisplacement and velocity
  3. CAcceleration, velocity and displacement
  4. DDisplacement and acceleration

Correct answer

B. Displacement and velocity

Step-by-step solution

When a tennis ball falls on the ground and bounces back, its velocity and displacement changes in reverse direction while direction of acceleration remains same.
