Question

Define elastic collision. Find expression for velocities of body after elastic collision.

Answer 1

Explanation:

An encounter between two bodies in which the total kinetic energy of both the bodies after the encounter is equal to their total kinetic energy before the encounter is called Elastic collision. Elastic collisions occur only when there is no net conversion of kinetic energy into different forms. A perfectly elastic collision is one wherein there no loss of kinetic energy during the collision. In any elastic collision, conservation of momentum and conservation of kinetic energy can be observed.

Answer 2

Answer:

elastic collision is the collision between two elastic bodies where the following conditions are maintained

I. kinetic energy is conserved

ii. total mechanical energy is conserve red

III. linear momentum is conserved

expression is

final velocity of body 2 - final velocity of body 1= initial velocity of body 1 - initial velocity of body 2

it is true for elastic collision
