general-sciencephysics-mechanics
- AIt moves with a uniform velocity.
- BIt moves with a uniform speed.
- CIt moves with a non-uniform acceleration.
- DIt moves with a uniform acceleration.
Explanation
A freely falling object, neglecting air resistance, is acted upon only by gravity and therefore accelerates uniformly at g (about 9.8 m/s^2). Its velocity and speed keep increasing, so it does not move with uniform velocity or uniform speed, and its acceleration is uniform rather than non-uniform. Hence option D.
