Question
Which of the following statements are true about collisions?
- During a collision, an object always encounters an impulse and a change in momentum.
- During a collision, the impulse which an object experience is equal to its velocity change.
- The velocity change of two respective objects involved in a collision will always be equal.
- While individual objects may change their velocity during a collision, the overall or total velocity of the colliding objects is conserved.
The correct answer is: During a collision, an object always encounters an impulse and a change in momentum.
