Question

what is co_ efficient of resituating? how it explains elastic and inelastic collision? ​

Answer 1

Answer:

Coefficient of restitution is the extent to which a body comes back to its original position after a collision with a second body. Clearly in a perfectly inelastic collision the value of this coefficient is zero as the two bodies merge as one.

Answer 2

Coefficient of restitution:

The coefficient of restitution is a quantity that represents the ratio of the final velocity to the initial velocity of two objects after they collide. Denoted by the symbol 'e', it can take on values between 0 and 1.

e = (relative velocity of separation) / (relative velocity of approach)

Elastic collision:

When the two objects involved in the collision bounce off each other without any loss of kinetic energy the collision is known as an elastic collision. Here, the relative velocity of separation is equal to the negative of the relative velocity of the approach. In an elastic collision, the coefficient of restitution is equal to 1.

Inelastic collision:

When the two objects stick together after the collision and there is a loss of kinetic energy then it is said to be an inelastic collision. In this case, the relative velocity of separation is less than the negative of the relative velocity of the approach. In Inelastic collision, the coefficient of restitution will be less than 1

The coefficient of restitution is used to anticipate the outcome of a collision between two objects.
