06a - Momentum and Collisions

An elastic collision is a type of collision where both momentum and kinetic energy are conserved.

In a perfectly inelastic collision, only momentum is conserved.

Impulse is the product of force and time.

In an inelastic collision, objects tend to 'stick' together after the collision.

The law of conservation of momentum states that the total momentum before a collision is equal to the total momentum after the collision.

Momentum is the product of an object's mass and its velocity (p = mv).

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, only momentum is conserved.

Impulse (J) = Force (F) × Time (t).

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².

Momentum increases with an increase in mass, as momentum (p) is directly proportional to mass (p = mv).
