Conceptual Impulse
Impulse is an object's change in momentum, Impulse states that the time it takes to change momentum
and the force required are inversely proportional. This means that a longer time takes less force and a
shorter time requires more force
Two friends are riding bikes next to each other and use the brakes to come point
to a stop. If one friend uses more force on the brakes, what can you say
about the time it takes them to stop?
It takes them more time to stop
It takes them less time to stop
It takes them the same amount of time to stop
