Impulse-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

How is impulse defined?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as Impulse = Force × Time.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object. This is expressed as Impulse = Δp = p_final - p_initial.

A runner has a momentum of 670 kg m/s and is traveling at a velocity of 9 m/s. What is his mass?

Back

74.4 kg

Front

How can a tennis ball and a bowling ball have the same momentum?

Back

They can have different speeds.

Front

What happens to momentum when the speed of an object is doubled?

Back

The momentum doubles.

Front

What is the formula for calculating momentum?

Back

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

Front

What is the unit of momentum?

Back

The unit of momentum is kg m/s.

Front

What is the effect of a net external force on the momentum of an object?

Back

A net external force changes the momentum of an object according to the impulse-momentum theorem.
