Momentum basics

Front

What is the equation to calculate momentum?

Back

p = mv

Front

How is momentum defined?

Back

Momentum is defined as Mass in Motion.

Front

What does Newton's Third Law state?

Back

For every action force, there is an equal and opposite reaction force.

Front

Calculate the momentum of a 1000-kg car moving northward at 20 m/s.

Back

20000 kg * m/s north

Front

What does the momentum of an object depend on?

Back

The momentum of an object depends on its mass and velocity.

Front

What is the unit of momentum?

Back

The unit of momentum is kg * m/s.

Front

If the mass of an object doubles, what happens to its momentum if velocity remains constant?

Back

The momentum also doubles.

Front

What is the relationship between force and momentum?

Back

Force is the rate of change of momentum.

Front

What is the formula for calculating impulse?

Back

Impulse = Change in momentum = Force x Time.

Front

What happens to momentum in a closed system?

Back

Momentum is conserved in a closed system.
