No. Elastic Collision Inelastic Collision
i. In an elastic collision, both momentum and kinetic energy are conserved. In an inelastic collision, momentum is conserved but kinetic energy is not conserved.
ii. The total kinetic energy after collision is equal to the total kinetic energy before collision. The total kinetic energy after the collision is not equal to the total kinetic energy before collision.
iii. Coefficient of restitution (e) is equal to one. Coefficient of restitution (e) is less than one. For a perfectly inelastic collision coefficient of restitution is equal to zero.
iv. Bodies do not stick together in elastic collision. Bodies stick together in a perfectly inelastic collision.
v. Sound, heat and light are not produced. Sound or light or heat or all of these may be produced.

A moving H-atom makes a head on perfectly inelastic collision with a stationary `Li^(++)` ion. Just before collision, both `- H` and `Li^(++)` are in

Correct Answer - `7.77 keV`

Supply of a product is perfectly price-inelastic. Its demand 'decreases'. This leads to fall in real national income. Other things remaining unchange.

Real national income measures GDP in real terms or only in terms of goods and services and not the prices. When the supply is perfectly inelastic, with a fall in...

Define perfectly inelastic collision. Give an example of it.

1. Collision in which the colliding bodies stick together after collision and move with a common velocity is called perfectly inelastic collision. 2. The loss in kinetic energy is maximum in...

Two bodies undergo one-dimensional, perfectly inelastic, head-on collision. Derive an expression for the loss in the kinetic energy.

USE 1) IF ELASTIC COLLISION THEN ENERGY CONSERVATION K.E.(INITIAL)=K.E.(FINAL) 2) IN INELASTIC USE MOMENTUM CONSERVATION
