Q. Consider the following statements regarding bodies in motion and free fall: - A body at rest has no inertia
- A body in free fall in vacuum has constant acceleration
- A body in free fall in vacuum has diminishing kinetic energy
Which of the above statements is / are correct?
Answer:
Only 2
Notes: Statement 1 is incorrect because all bodies, whether at rest or in motion, possess inertia. Statement 2 is correct; in a vacuum, a freely falling body accelerates at a constant rate due to gravity. Statement 3 is incorrect, as kinetic energy increases, not diminishes, while the object continues falling.
