NEETPhysicsMotion in One Dimension

Is the following statement regarding one-dimensional motion true or false, and provide reasons and examples accordingly:

Options

  1. ATrue, because acceleration depends on changes in velocity, not just the velocity at a single instant.
  2. BFalse, because zero speed implies zero acceleration.
  3. CTrue, because acceleration can be nonzero even when speed is zero, for example, during instantaneous changes i
  4. DFalse, because acceleration is always zero when speed is zero.

Correct answer

C. True, because acceleration can be nonzero even when speed is zero, for example, during instantaneous changes i

Step-by-step solution

Correct Option is : (C) True, because acceleration can be nonzero even when speed is zero, for example, during instantaneous changes in direction.
