PHYIC CALCULATOR
Coefficient of Restitution Calculator
A precise tool.
What is the Coefficient of Restitution Calculator & How does it work?
The coefficient of restitution (e) is a measure of the elasticity of a collision between two objects. It is defined as the ratio of the relative velocity of separation to the relative velocity of approach. The value of e ranges from 0 to 1, where 0 indicates a perfectly inelastic collision and 1 indicates a perfectly elastic collision.In this calculator, you can input the pre- and post-collision velocities of two objects to determine the coefficient of restitution.
e = -frac{v_2′ – v_1′}{v_2 – v_1}
v_1 = initial velocity of the first object
v_2 = initial velocity of the second object
v_1′ = final velocity of the first object
v_2′ = final velocity of the second object
v_2 = initial velocity of the second object
v_1′ = final velocity of the first object
v_2′ = final velocity of the second object

Frequently Asked Questions
What is the coefficient of restitution?
The coefficient of restitution is a measure of how elastic a collision is, ranging from 0 (perfectly inelastic) to 1 (perfectly elastic).
How do I calculate the coefficient of restitution?
Use the formula e = -(v2′ – v1′) / (v2 – v1), where v1 and v2 are initial velocities, and v1′ and v2′ are final velocities.
What does a coefficient of restitution of 0.5 mean?
A coefficient of restitution of 0.5 indicates that the collision is moderately elastic, with some energy lost as heat or deformation.
Can the coefficient of restitution be greater than 1?
No, the coefficient of restitution cannot be greater than 1; it ranges from 0 to 1.
Why is the coefficient of restitution important in physics?
It helps in understanding how energy is conserved or lost during collisions and is crucial in fields like sports engineering and automotive safety.
