1. On the highway of life, are you the bug or the windshield?

2. Bug hits windshield

3. The force on each is…
The same- Newton’s third law - You can only exert back as much force is exerted on you

4. The time of impact is…
The same- It would be impossible for the bug to hit the windshield for 2 seconds while the windshield hits the bug for 3 seconds

5. The change of velocity on each is…
Very Different – Newton’s First Law -The car, hardly noticeable. The bug very noticeable. The bug slows down, stops and reverses direction

6. The momentum before and after…
The same – Newton’s Second law momentum is conserved in a collision

7. What about a BIGGER BUG?

8. The force on each is…
The same- Newton’s third law - You can only exert back as much force is exerted on you

9. The time of impact is…
The same- It would be impossible for the bug to hit the windshield for 2 seconds while the windshield hits the bug for 3 seconds

10. The change of velocity on each is…
Slightly Different – Newton’s First Law- The car, slows down noticeably, The bug slows down stops and reverses direction

11. So Why Does the bug go splat, but a windshield doesn’t

12. Its only a Small force when a bug hits the windshield
It only takes a small force to kill a bug. That same size force won’t hurt the windshield

13. The difference, the size of the force and momentum,
the smaller bug has less force and change in momentum, the bigger bug has more force and change in momentum.

14. What if the bug is the same mass and same speed as a car?

15. They both stop.
