5480 Conservation of Momentum

Front

What is the principle of conservation of momentum?

Back

The principle states that the total momentum of a closed system remains constant if no external forces act on it.

Front

Define inelastic collision.

Back

An inelastic collision is a type of collision where kinetic energy is not conserved, and the objects may stick together after the collision.

Front

Define elastic collision.

Back

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

Front

What happens to momentum in a closed system during a collision?

Back

The total momentum before the collision is equal to the total momentum after the collision.

Front

What is an example of an inelastic collision?

Back

A student runs and jumps onto a shopping cart, causing both to move together.

Front

What is an example of an elastic collision?

Back

A ball hitting a racquet and bouncing back with the same speed.

Front

If a person on a skateboard throws a bowling ball, what happens to the skateboard's velocity?

Back

The skateboard will move in the opposite direction to conserve momentum.

Front

What is the relationship between force and momentum during a collision?

Back

The force experienced by two colliding objects is equal and opposite, according to Newton's third law.

Front

What is the formula for momentum?

Back

Momentum (p) is calculated as p = mass (m) × velocity (v).

Front

What is the effect of a collision on the momentum of the involved objects?

Back

One object may lose momentum while the other gains momentum, keeping the total momentum constant.
