Momentum Practice

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

What is the formula for calculating momentum?

Back

p = mv, where p is momentum, m is mass, and v is velocity.

Front

If a runner has a momentum of 670 kg m/s and is travelling at a velocity of 9 m/s, what is his mass?

Back

74.4 kg

Front

Which car has more momentum if the red car and the blue car have the same mass, but the blue car is moving faster?

Back

The blue car has more momentum.

Front

What takes more force to catch, a bowling ball or a ping pong ball, both moving at 3 m/s?

Back

A bowling ball because it has more mass.

Front

Which object has the greatest momentum: A 0.05 kg object rolling at 0.2 m/s, A 0.15 kg object rolling at 2 m/s, A 0.15 kg object rolling at 1 m/s, or A 0.4 kg object rolling at 2 m/s?

Back

A 0.4 kg object rolling at 2 m/s.

Front

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

Back

The momentum increases.

Front

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

Back

The momentum increases.

Front

Is momentum a scalar or vector quantity?

Back

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

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.
