Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula P = m * v.

Front

What is the formula for calculating momentum?

Back

The formula for momentum (P) is P = m * v, where m is mass and v is velocity.

Front

What is the unit of momentum?

Back

The unit of momentum is kg*m/s.

Front

How do you calculate the momentum of an object?

Back

To calculate momentum, multiply the mass of the object (in kg) by its velocity (in m/s).

Front

If a 50 kg ball rolls at 5 m/s, what is its momentum?

Back

250 kg*m/s.

Front

What is the unit for mass?

Back

kg.

Front

What is the unit for velocity?

Back

m/s.

Front

What is a positive change in momentum (ΔP)?

Back

A positive change in momentum occurs when an object's momentum increases, such as when a truck accelerates.

Front

If a 3,500 kg truck increases its velocity from 7 m/s to 11 m/s, what is the change in momentum?

Back

14,000 kg*m/s.

What happens to momentum in a closed system?

Back

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