Calculating Momentum

Front

What is momentum?

Back

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

Front

What is the formula for calculating momentum?

Back

The formula for calculating momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

If a 55kg person is running at 7 m/s, what is their momentum?

Back

The momentum is 385 kg·m/s.

Front

How do you calculate mass if you know momentum and velocity?

Back

Mass can be calculated using the formula m = p/v, where p is momentum and v is velocity.

Front

If a runner has a momentum of 720 kg m/s and is traveling at a velocity of 5 m/s, what is his mass?

Back

The mass is 144 kg.

Front

How do you find velocity if you know momentum and mass?

Back

Velocity can be found using the formula v = p/m, where p is momentum and m is mass.
