Elastic — Equal Mass ExchangeMediumQuestion 30530
Question
Newton's cradle works on the principle that in elastic collisions between equal masses in a line:
- AAll masses move
- BOnly momentum is transferred to the end ball
- CThe end ball moves with speed equal to the original ballCorrect
- DEnergy is lost at each bounce
Correct answer
The end ball moves with speed equal to the original ball
Explanation
In Newton's cradle, elastic collisions between equal masses transfer velocity completely from one end to the other. The end ball receives the entire velocity of the striking ball.
