General KnowledgePhysics
- AIts acceleration
- BIts momentum
- CIts kinetic energy
- DIts potential energy SOLVED papEr : 2022 (II)
Explanation
A freely falling object accelerates uniformly at g (neglecting air resistance). Its momentum, kinetic energy and potential energy all change continuously during the fall. Hence its acceleration remains uniform.
