Momentum & Impulse

Front

What is the equation for impulse?

Back

Impulse = Force x Time

Front

What is the formula for momentum?

Back

Momentum = Mass x Velocity

Front

What does the impulse-momentum theorem state?

Back

The impulse on an object is equal to the change in momentum it causes.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

How do you calculate the force exerted on an object?

Back

Force = Change in Momentum / Time

Front

What is the unit of impulse?

Back

Newton-second (Ns) or kg*m/s.

Front

If a 5kg ball has a momentum of 30 kg*m/s, what is its speed?

Back

6 m/s

Front

What happens to momentum in a closed system?

Back

Momentum is conserved.

Front

What is the relationship between impulse and force?

Back

Impulse is the product of force and the time duration over which it acts.

Front

What is the significance of a negative impulse?

Back

A negative impulse indicates a decrease in momentum.
