[elitem94]

so what type of collision would this be, elastic or inelastic or perfectly inelastic? thats pretty much my trouble in this subject. but excellent video

[PhysicsEH]

@elitem94 With momentum it does not matter if it is elastic or inelastic. The momentum equations work for all conditions. If the 2 objects stick together it is a very non elastic collision but that does not change how you apply the momentum equations. You only need to know if it's elastic when you are going to use energy equations. I hope this helps.

Hey, when you have formulate the equation for the P before= P after, is this assuming that no energy has been converted to other forms like heat and sound? Or does this equation take all factors into account?

[PhysicsEH]

@64647936 Answer Part 1: It does assume that no momentum was added to the system (like another object entering the collision) or no momentum was lost (as in a piece breaking off and leaving that was not accounted for).

Thank you for the video, I am brand new to the topic, therefore you help me understand this subject.

OMGGGG. THE CHALK AND THE BOARD <3

[hypeblast]

hey how can i find simple understanding, on angular momentum ?

[PhysicsEH]

@64647936 Glad to help.
