A
Impulse - force * time
1
Q
What is an impulse ?
A
The effect of a force acting over a period of time
2
Q
What is the measurement for an impulse ?
A
Newton seconds
3
Q
How can an impulse be used to increase momentum ?
A
- can happen through increasing muscular force
- E.g. Basketball: Larger force is generated for a higher jump
- Can also happen through have an increased time that the force is allowed
- E.g. Hammerthrow: Using 3/4 spins rather than just a single rotation
4
Q
How can an impulse be used to decrease the momentum ?
A
- by increasing the time forces act upon them
5
Q
What is a net impulse ?
A
A combination of positive and negative impulses
