Specification

Elastic and Inelastic Collisions

ELASTIC: – Kinetic energy is conserved

INELASTIC: – Some (or all) Kinetic energy is transformed into thermal or other forms of energy.

In both types of collisions:

Total energy and momentum are conserved.

Elastic and Inelastic Collisions

Summary of Collisions

Derive the equation of the Coefficient of Restitution

Explosions

KINETIC energy is increased

Both the total energy and momentum are conserved

Energy in Collisions

Newton’s Laws of Motion

First Law:

The momentum of a particle remains constant unless an external force acts on the particle: p = constant

Second Law:

The resultant force acting on a body is equal to the rate of change of its momentum: F = Δp/Δt

Third Law:

When two bodies exert action and reaction forces to each other, their changes of momentum are equal and opposite.
