When a light-weight body and a massive body are acted upon by the same force for the same period of time, the
- A. momenta of both bodies remain the sameCorrect
- B. lighter body has a higher momentum
- C. massive body has a higher momentum
- D. massive body builds up a higher velocity
Explanation
Since both bodies are acted on by the same force for the same time, the change in momentum experienced by both bodies is the same (Newton's second law); hence momenta of both bodies remain the same.
