With a plastic impact, the coeffecient of restitution is 0.

With an elastic impact, the coeffecient of restitution is 0<e<1.

With an inelastic impact, the coeffecient of restitution is 1.

### Why the value of coefficient of restitution of a perfectly plastic impact is 0?

Physicists distinguish between elastic and inelastic (and partially elastic) collisions. If you mean "elastic", the coefficient of restitution is 1. If you mean "inelastic", the coefficient of restitution is 0.Why? Because that's how "elastic" and "inelastic" collisions are DEFINED. If all the kinetic energy is maintained, the coefficient (relative speed after collision, divided by relative speed before the collision) is 1 - i.e., no movement is lost. If it is zero, all the movement energy (relative speed) is lost.

### What is elastic and inelastic collisions in terms of momentum?

In elastic collisions, both momentum and kinetic energy are conserved. This means that momentum before and after the collision is the same, and the objects bounce off each other without any loss of kinetic energy. In inelastic collisions, momentum is conserved but kinetic energy is not. Some kinetic energy is converted into other forms of energy, such as heat or sound, during the collision.

### Which type of collision occurs when a baseball bat hits a baseball?

inelastic collision The formulas for the velocities after a one-dimensional collision are: where V1f is the final velocity of the first object after impact V2f is the final velocity of the second object after impact V1 is the initial velocity of the first object before impact V2 is the initial velocity of the second object before impact M1 is the mass of the first object M2 is the mass of the second object CR is the coefficient of restitution; if it is 1 we have an elastic collision; if it is 0 we have a perfectly inelastic collision

its a collision

### How do you determine if a collision was elastic inelastic or perfectly inelastic?

just check momentum before and after and if they're the same then elastic if not then inelastic.

### What is the difference in elastic collision and inelastic collision?

Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.

### What is the value of coefficient of restitution for the perfectly plastic body?

the coefficient of restitution for the perfectly plastic body is zero(0). the coefficient of restitution for the perfectly elastic body is one(1).

### What is elastic and inelastic collision?

In an elastic collision, both kinetic energy and momentum are conserved. This means that there is no net loss of energy during the collision. In an inelastic collision, kinetic energy is not conserved, and some of the energy is transformed into other forms such as heat or sound.

### What is the value of coefficient of restitution for the perfectly elastic body?

It is 1. A value of 0 is perfectly inelastic, but examples of objects where it is 1 are hard to come by. (eg. 2 electrons colliding.)

### 1 In a collision that is inelastic the total what after the collision is not the same as before the collision?

Hi, in line with Newton's laws of motion the momentum before and after a collision is always conserved (when no external force is applied to change the systems momentum). In elastic collisions we can apply the conservation of momentum and conservation of energy principles. In inelastic collisions we can only apply the conservation of momentum principle. Energy is not conserved in inelastic collisions because energy is lost through small deformations, noise, friction, etc. We can compute the coefficient of restitution that helps determine this degree of energy loss from impulse-momentum equations.

### Distinguish beween and elastic and inelastic collision for wich type of collision is momentum conserved?

Momentum is conserved in both elastic and inelastic collisions. Mechanical energy is conserved only in elastic collisions. In inelastic collisions, part of the energy is "lost" - usually most of it would be converted to heat, eventually.
