Question

define elastic and non elastic collision

Answer 1

Please mark is as a brainlist

Hope helpful for you
An elastic collision is defined as one in which both conservation of momentum and conservation of kinetic energy are observed. This implies that there is no dissipative force acting during the collision and that all of the kinetic energy of the objects before the collision is still in the form of kinetic energy afterward.

While

An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision

Answer 2

$\large{\underline{\textrm{Collision:-}}}$

• If motion of one object affects the motion of other object, then we say that collision occurs
• It is not necessary that they physically collide.

$\frak{Collision}\begin{cases}\sf{elastic\: collision}\\ \ \sf{Inelastic\: collision}\end{cases}$

• In both the collision total energy and total momentum is conserved.
• In elastic collision kinetic energy is also conserved.
• In perfect Inelastic collision, after collision the two bodies stick together .
