Impulse-Momentum

Front

What is impulse?

Back

Impulse is the product of the average force applied to an object and the time duration over which the force is applied. It is measured in Newton-seconds (N⋅s).

Front

What is the formula for calculating impulse?

Back

Impulse (J) = Force (F) × Time (t)

Front

How is momentum defined?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity and is measured in kg⋅m/s.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = Mass (m) × Velocity (v)

Front

If a 75 kg biker is moving at 5 m/s, what is their momentum?

Back

375 kg m/s

Front

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

Back

The momentum doubles.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object. J = Δp.

Front

What is the unit of momentum?

Back

The unit of momentum is kg⋅m/s.

Front

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

Back

The momentum of an object at rest is 0 kg m/s.

Front

Which has more momentum: a bowling ball or a ping pong ball traveling at the same velocity?

Back

The bowling ball has more momentum because it has a greater mass.
