Solution

The correct option is B False

Speed:

  • The rate of change of position of an object in any direction.
  • SI unit is ms-1.
  • It is a scaler quantity.

Velocity:

  • The rate of change of the object's position with respect to a frame of reference and time.
  • It is a vector quantity.
  • The magnitude of velocity is the instantaneous speed of the object.

Constant acceleration:

  • If the velocity of the particle changes at a constant rate, then this rate is known as constant acceleration.

When a particle moving with constant acceleration:

  • Speed can never be negative while the magnitude of velocity may be negative as the acceleration is constant.

Hence, the given statement is false.
