Momentum

Front

What is momentum?

Back

Momentum is a measure of the motion of an object, calculated as the product of its mass and velocity (p = mv).

Front

What factors affect momentum?

Back

Momentum depends on two factors: mass and velocity.

Front

What is the formula for calculating momentum?

Back

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

Front

If an object is at rest, what is its momentum?

Back

An object at rest has zero momentum because its velocity is zero.

Front

How do you calculate the momentum of a moving object?

Back

To calculate momentum, multiply the object's mass by its velocity (p = mv).

Front

What is the unit of momentum?

Back

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

Front

If a 50 kg object is moving at 10 m/s, what is its momentum?

Back

The momentum is 500 kg m/s (p = 50 kg * 10 m/s).

Front

What is the relationship between mass and momentum?

Back

Momentum increases with an increase in mass if velocity remains constant.

Front

What is the relationship between velocity and momentum?

Back

Momentum increases with an increase in velocity if mass remains constant.

Front

If a runner has a momentum of 670 kg m/s and is traveling at 9 m/s, what is his mass?

Back

The mass is 74.4 kg (mass = momentum/velocity = 670 kg m/s / 9 m/s).
