Inelastic and elastic collision (please explain)

AI Thread Summary
In a perfectly inelastic collision, two objects stick together and move as one, which can result in them stopping if their initial momentum is zero. In contrast, during an elastic collision, momentum and kinetic energy are conserved, meaning the objects will not stop but rather bounce off each other. It is important to understand that while kinetic energy may be lost in inelastic collisions, momentum is always conserved. Therefore, the statement that both objects will stop in an elastic collision is false. Overall, momentum conservation is key in analyzing both types of collisions.

Homework Statement


If a object 1 & 2 collide as a perfectly inelastic collision, would they will both stop. Also If this same situation happened elastic? please explain if this is true or false and draw a free body diagram if possible.

Homework Equations


F=ma
Newton second Law
KE=1/2ma

The Attempt at a Solution


true for inelastic, false for elastic because the momentum energy will transfer.

We have to realize that momentum is conserved for all collisions hence even in any inelastic collision kinetic energy cannot be completely lost unless the total initial momentum is zero. Think it over.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
