Collision

Question 1

What is the co-efficient of Restitution, e?

Answer 1

e = Velocity of Separation / Velocity of Approach

Question 2

What values can, e, the coefficient of restitution take?

Answer 2

e, the coefficient of restitution can take values only from 0 to 1, i.e

0 ≤ e ≤ 1

e = 0, implies the collision is perfectly elastic
e = 1, implies the collision is perfectly inelastic
For any other value of e, implies collision is partly elastic
