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 unit for momentum?

Back

The unit for momentum is kg m/sec.

Front

How does momentum change when the speed of an object is doubled?

Back

When the speed of an object is doubled, its momentum also doubles.

Front

Calculate the momentum of a 50 kg ball rolling at 5 m/s.

Back

The momentum is 250 kg*m/s.

Front

If an object has a momentum of 40 kgm/s and a mass of 60 kg, what is its velocity?

Back

The velocity is 0.67 m/s.

Front

Which has more momentum: a car stopped at a red light or a bike moving at 15 mph?

Back

The bike has more momentum.

Front

What is the formula for calculating momentum?

Back

The formula for calculating momentum is p = mv.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum remains constant, according to the law of conservation of momentum.

Front

Define conservation of momentum.

Back

Conservation of momentum states that the total momentum of a closed system before and after an event is the same, provided no external forces act on it.

Front

What is the relationship between mass and momentum?

Back

Momentum is directly proportional to mass; as mass increases, momentum increases if velocity remains constant.
