06a - Momentum and Collisions

Front

What is an elastic collision?

Back

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

Front

What is conserved in a perfectly inelastic collision?

Back

In a perfectly inelastic collision, only momentum is conserved.

Front

What is impulse?

Back

Impulse is the product of force and time.

Front

What happens in an inelastic collision?

Back

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

Front

What does the law of conservation of momentum state?

Back

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

Front

Define momentum.

Back

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

Front

What is the difference between elastic and inelastic collisions?

Back

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

Front

What is the formula for calculating impulse?

Back

Impulse (J) = Force (F) × Time (t).

Front

What is kinetic energy?

Back

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

Front

How does mass affect momentum?

Back

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