Question

define elastic collision for one dimension

Answer 1

 the conservation of kinetic energy, which tells us that the total kinetic energy must be the same before and after the collision. You'll use these two conservation equations constantly when working on problems that involveone-dimensional elastic
collisions.

Answer 2

• one-D elastic collision is the one in which the objects continue to move along the same original straight line and there is no loss or gain in Kinetic energy.
