Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v)

Front

Which object has the most momentum if they are all rolling at the same velocity: a rolling ping-pong ball, a rolling bowling ball, a rolling soccer ball, or a rolling basketball?

Back

The rolling bowling ball has the most momentum.

Front

Calculate the momentum of a 50 kg ball rolling at 5 m/s.

Back

Momentum = 50 kg × 5 m/s = 250 kg*m/s.

Front

What is the unit for mass?

Back

The unit for mass is kilograms (kg).

Front

What is the unit for velocity?

Back

The unit for velocity is meters per second (m/sec).

Front

In order for an object to have momentum, it must be ________

Back

moving.

Front

If an object is at rest, what is its momentum?

Back

The momentum is zero because momentum depends on velocity.

Front

What factors affect the momentum of an object?

Back

Momentum is affected by the object's mass and its velocity.

Front

How does increasing the mass of an object affect its momentum, assuming velocity remains constant?

Back

Increasing the mass of an object increases its momentum.
