MOre specifically there are usually formulas which pertain to only one of those types of collisions.

Ex: [itex] (v_1-v_2)_i = -(v_1-v_2)_f [/itex]

Does anyone know more of these types of formulas, or tricks to solve these equations?

Thanks.

Sure, your textbook.Does anyone know more of these types of formulas

- you can always use momentum conservationor tricks to solve these equations?

- in elastic collisions, you can use energy conservation in addition

- in perfectly inelastic collisions, the objects stick together afterwards, so they have the same velocity

- in the center of mass system, all those collisions are easy to study

All equations are just a result of those ideas.

Inelastic collisions: KE is not conserved, momentum is conserved.

This is a reasonable starting point

if masses of two objects is same than in elastic collision there velocities get interchanged and if masses are not equal than you can use the formula which u have given for elastic collision.
