Momentum Calculations

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the equation p=mv.

Front

What is the unit of momentum?

Back

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

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

Front

What does the term 'impulse' refer to in physics?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

If an object has a mass of 2 kg and is moving at a velocity of 3 m/s, what is its momentum?

Back

The momentum is 6 kg*m/s (p = 2 kg * 3 m/s).

Front

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).

Front

What is the formula to find mass if momentum and velocity are known?

Back

The formula to find mass is m = p/v.

Front

What is the effect of increasing mass on momentum if velocity remains constant?

Back

If mass increases while velocity remains constant, momentum increases.
