Momentum Warm-Up

Front

What is momentum?

Back

Momentum is defined as 'Mass in Motion'. It is the product of an object's mass and its velocity.

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula: p = mass (m) × velocity (v).

Front

What are the units of momentum?

Back

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

Front

If a cart has a mass of 0.250 kg and is moving at 0.400 m/s, what is its momentum?

Back

0.1 kg-m/s.

Front

Which has more momentum: a stationary object or a moving object of the same mass?

Back

The moving object has more momentum because momentum depends on velocity.

Front

What factors affect the momentum of an object?

Back

The momentum of an object depends on its mass and velocity.

Front

Which has the least amount of momentum? An ant walking, an ant at rest, an elephant walking, or an elephant running?

Back

An ant at rest has the least amount of momentum.

Front

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

Back

The momentum of the object will also double.

Front

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

Back

The momentum of an object at rest is 0 kg-m/s.

Front

What is the relationship between mass, velocity, and momentum?

Back

Momentum is directly proportional to both mass and velocity; if either increases, momentum increases.
