MHT CET · Physics · Motion In One Dimension
Five objects of different masses are simultaneously released vertically downwards from height 'h' (in air). Which physical quantity associated with the objects will change at the instant they strike the ground ? (Neglect the air resistance.)
- A Momentum
- B Time
- C Acceleration
- D Velocity
Answer & Solution
Correct Answer
(A) Momentum
Step-by-step Solution
Detailed explanation
\( \text{The objects change from having a non-zero velocity to zero (or reverse velocity) upon impact.} \) \( \text{Since velocity (v) changes, and momentum (p = mv) is directly proportional to velocity,} \)
