Impulse = area under the curve on a Force/time graph
This is still true if the force is variable:
Change in momentum = area under the curve on a Force / time graph
The change in momentum can be due to a small force acting over a long time.
The change in momentum can be due to a large force acting over a short time.
Besides running a car into a haystack or a brick wall think of bringing yourself to a stop
- by running into a solid dash board or instrument panel
- by running into a padded dashboard
- by using shoulder belts.
- How do these different ways of stopping affect the time required to stop and how do they effect the force you experience as you come to a stop?
