Momentum

Front

What does momentum depend on?

Back

Momentum depends on an object's mass and velocity.

Front

What is the unit for velocity?

Back

The unit for velocity is m/sec.

Front

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

Back

The rolling bowling ball has the most momentum.

Front

If an object has a momentum of 40 kg x m/s and a mass of 60 kg, what is its velocity?

Back

The velocity is 0.67 m/s.

Front

What is the unit for mass?

Back

The unit for mass is kg.

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating momentum?

Back

The formula for momentum (p) is p = mass (m) x velocity (v).

Front

If an object has a mass of 10 kg and a velocity of 5 m/s, what is its momentum?

Back

The momentum is 50 kg x m/s.

Front

What happens to momentum if the mass of an object increases while its velocity remains constant?

Back

If the mass increases, the momentum increases.

Front

What is the principle of conservation of momentum?

Back

The principle states that in a closed system, the total momentum before an event is equal to the total momentum after the event.
