An object is dropped from a height onto the floor. Which one of the following remains uniform as it falls?

  1. A. Its acceleration
  2. B. Its momentum
  3. C. Its kinetic energy
  4. D. Its potential energy

Correct Answer: A. Its acceleration

Explanation

When an object falls freely under the influence of gravity (ignoring air resistance), its acceleration remains constant at g (approximately 9.8 \text{ m/s}^2), while its velocity, momentum, kinetic, and potential energies continuously change.
