## What is coefficient of restitution formula?

Coefficient of Restitution = speed up/speed down. Where v = velocity, g = 9.8m/s2, and h = average height measured. We took the average of the bounced height value (h) and put it in the formula along with the initial height (H) of 92 cm.

**What is a good coefficient of restitution?**

The coefficient of restitution (COR, also denoted by e), is the ratio of the final to initial relative speed between two objects after they collide. It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision.

### What is the coefficient of restitution for a plastic collision?

The coefficient of restitution exists as a number between 0 and 1. In a perfectly inelastic collision, the difference in the velocities of two objects after a collision is zero because those objects stick together. This means that the coefficient of restitution for a perfectly inelastic collision is e = 0.

**What is the coefficient of restitution for elastic impact?**

For an elastic collision coefficient of restitution is 1.

#### Why is coefficient of restitution used?

Coefficient of restitution is typically considered as an appropriate measure of bat performance as it has a significant effect on the post-impact velocity of the ball. It represents the ratio of the relative velocity between the ball and bat immediately after impact and immediately before impact.

**How do you measure restitution?**

In restitution, the damages are calculated based on how much the defendant gained from the process. In most cases, this is an amount used to restore what was lost in a civil lawsuit. In terms of compensation, the damages are calculated based on how much the plaintiff lost. This is often paid to the victim of a crime.

## What happens if the coefficient of restitution is 0?

The coefficient of restitution always satisfies 0≤e≤1. When e=0, the balls remain in contact after the collision. When e=1, the collision is elastic: there is no loss of kinetic energy.

**What is the coefficient of restitution if it is 0 or 1?**

The coefficient of restitution (COR) also denoted by (e) is the ratio of the final to initial relative velocity between two objects after they collide. It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision.

### Can coefficient of restitution be greater than 1?

Yes. 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.

**What is coefficient of restitution how it explains elastic and inelastic collision?**

Answer: The coefficient of restitution (COR) is the ratio of the final to initial relative velocity between two objects after they collide. A perfectly inelastic collision has a coefficient of 0, but a 0 value does not have to be perfectly inelastic.

#### What does coefficient of restitution depends on?

Coefficients of restitution depend on factors including material properties, body geometry, and impact velocity. Applying a coefficient of restitution to your mechanism simulates nonrigid properties in a rigid body calculation. For example, a perfectly elastic collision has a coefficient of restitution of 1.

**How does coefficient of restitution relate to sports?**

The coefficient of restitution (or COR) is a measure of the energy that is lost during impact. Balls with higher COR will be more lively in play. While it is close to 0.5 for most balls, it can range from 1 (no energy lost) to 0 (all energy lost).
