An object is dropped from a height onto the floor. Which one of the following remains uniform as it falls?
- A. Its acceleration ✓
- B. Its momentum
- C. Its kinetic energy
- 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.
