Question
What is the difference between head-on collision and glancing collision? Define coefficient of restitution.
✓
Answer
Head-on collision: If the bodies move along the same straight line before and after collision it is called headon collision.
Glancing collision: If the bodies do not move along the same straight line after the collision it is called glancing collision.
Coefficient of restitution: It is the measure of degree of elasticity of a collision and is defined as.
$\text{e}=\frac{\text{relative speed of separation after collision}}{\text{relative speed of approach before collision}}$
Glancing collision: If the bodies do not move along the same straight line after the collision it is called glancing collision.
