Assertion: In a perfectly inelastic collision in the absence of external forces , the kinetic energy is never conserved.
Reason: The objects deformed and stick together in this type of collision.

In an elastic collision in absence of external force, which of the following is /are correct

In an elastic collision in absence of external force, which of the following is/are correct :

In a perfectly inelastic direct collision maximum transfer of energy takes place if-

What is a perfectly inelastic collision? Show that kinetic energy is invariably lost in such a collision.

During collision kinetic energy is conserved at each instant

In an inelastic collision, the kinetic energy after collision

(a) Explain perfect inelastic collision and derive an expression for loss of kinetic energy in perfect inelastic collision.

Assertion: In an elastic collision of two bodies , the momentum and energy of each body is conserved. Reason: If two bodies stick to each other , after colliding , the collision is said to be perfectly elastic.
