Momentum

Front

What are the units of Force?

Back

Newtons (N)

Front

How is momentum calculated?

Back

Momentum is calculated as the product of mass and velocity (p = m * v).

Front

What is the formula for momentum?

Back

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

Front

What factors affect the momentum of an object?

Back

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

Front

If a 1000-kg car is moving at 20 m/s, what is its momentum?

Back

20000 kg*m/s north.

Front

Which has more momentum: a moving car or an ant at rest?

Back

A moving car has more momentum than an ant at rest.

Front

What is the momentum of an object at rest?

Back

The momentum of an object at rest is zero.

Front

If a runner has a momentum of 670 kg*m/s and is traveling at 9 m/s, how do you find his mass?

Back

Use the formula m = p / v, so mass = 670 kg*m/s / 9 m/s = 74.4 kg.

Front

What is the relationship between mass and velocity in terms of momentum?

Back

Momentum increases with an increase in either mass or velocity.

Front

Can an object have momentum if it is not moving?

Back

No, an object must be in motion to have momentum.
