# What is coefficient of restitution formula?

## What is coefficient of restitution formula?

v 2−v 1=−e(u 2−u 1). This formula is Newton’s law of restitution. The coefficient of restitution always satisfies 0≤e≤1. When e=0, the balls remain in contact after the collision. Newton’s law follows from the supposition that, for each body, the impulse during restitution is e times the impulse during deformation.

### What material has the highest coefficient of restitution?

Super Ball

The Super Ball is almost perfectly elastic in both the horizontal and vertical directions. The Super Ball has an almost perfect coefficient of restitution and does things other balls do not.

#### What is the coefficient of restitution What is it’s significance?

The coefficient of restitution is important because it is what determines whether a collision is elastic or inelastic in nature. Determining whether a collision is elastic or not shows if there is any form of loss of kinetic energy as a result of the collision.

**How do I find the coefficient of restitution?**

The coefficient of restitution is found by the formula Coefficient of Restitution = speed up/speed down. In order to find speed we had to use the average height, that we measured, and put it in the formula

**Can the coefficient of restitution be greater than 1?**

If a body explodes then Coefficient of restitution can be greater than 1. Going by the definition of Coefficient of restitution, it is simply the ratio between relative velocities of particles before and after an interaction. Mathematically, it is capable of assuming values greater than 1.

## Why is the coefficient of restitution important?

The coefficient of restitution is important because it tells us whether a collision is elastic or inelastic.

### What is the abbreviation for coefficient of restitution?

C.O.R. stands for Coefficient of Restitution (also Centro Operativo Regionale and 2 more)
