Impulse Flashcards
1
Q
What is impulse?
A
Impulse is the change in momentum of an object
Impulse = Force x Time
The greater the impulse = the greater the change in momentum
2
Q
How can we decrease the momentum?
A
By increasing the time over which we change an objects mometum, the force decreases and thus impulse stays the same.
Used in sports to reduce the risk of injury and increase the likelihood of success.
