Momentum

Front

What is momentum?

Back

Momentum is a measure of the motion of an object, calculated as the product of its mass and velocity.

Front

What is the formula for calculating momentum?

Back

Momentum = Mass x Velocity

Front

Which object has more momentum: a heavy truck moving slowly or a light car moving quickly?

Back

The light car moving quickly may have more momentum, depending on its speed.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before and after an event remains constant.

Front

What is the unit of momentum?

Back

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

Front

If two objects collide and no external forces act on them, what happens to their total momentum?

Back

The total momentum before the collision equals the total momentum after the collision.

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.

Front

How does velocity affect momentum?

Back

Greater velocity results in greater momentum if mass is constant.

Front

What is the momentum of a 2 kg object moving at 3 m/s?

Back

Momentum = 2 kg x 3 m/s = 6 kg·m/s.

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.
