Momentum

Front

What is the definition of momentum?

Back

Momentum is defined as mass in motion.

Front

If a 9 kg blob moving at 5 m/s collides and sticks to a 5 kg blob, what is the final velocity of the combined blobs?

Back

The final velocity of the two blobs is 3.2 m/s.

Front

How do you calculate the momentum of an object?

Back

Momentum is calculated using the formula: Momentum = Mass × Velocity.

Front

What is the momentum of a 1000-kg car moving northward at 20 m/s?

Back

The momentum is 20000 kg*m/s north.

Front

What happens to the momentum of an object when its speed is doubled?

Back

When the speed of an object is doubled, its momentum also doubles.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg*m/s).

Front

How does mass affect momentum?

Back

Momentum is directly proportional to mass; as mass increases, momentum increases if velocity remains constant.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before and after an event remains constant.

Front

In a perfectly elastic collision, how is momentum conserved?

Back

In a perfectly elastic collision, both momentum and kinetic energy are conserved.
