ELASTIC COLLISION:
"The collision in which both linear momentum and K.E are conserved is said to be elastic collision".
OR
"In the ideal case when no K.E is lost, the collision is said to be perfectly elastic".
For instance, when a hard ball is dropped onto a marble floor, it rebounds to very nearly the initial height. It loses negligible amount of energy in the collision with the floor.
KINEMATIC CHAIN : Refers to an assembly of rigid bodies connected by joints that is the mathematical model for a mechanical system. As in the familiar use of the word chain, the ri
