The Impact of Life: Understanding Forces Through the Bug and Windshield Analogy

DESCRIPTION

On the highway of life, are you the bug or the windshield? This intriguing analogy illustrates Newton's third law of motion, demonstrating how forces act during collisions. When a small bug meets a windshield, both experience equal force but with vastly different outcomes. The small bug, with little force needed to change its momentum, goes splat, while the windshield remains largely unaffected. Investigate the physics of collisions, momentum conservation, and the significant differences between small and large masses in motion.

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

  2. Bug hits windshield

  3. Bug hits windshield

  4. The force on each is… The same- Newtons third law You can only exert back as much force is exerted on you

  5. 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

  6. The change of velocity on each is… Very Different – The car, hardly noticeable. The bug very noticeable. The bug slows down, stops and reverses direction

  7. The momentum before and after… The same – momentum is conserved in a collision

  8. What about a BIGGER BUG?

  9. The force on each is… The same- Newtons third law You can only exert back as much force is exerted on you

  10. 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

  11. The change of velocity on each is… Slightly Different – The car, slows down noticeably, The bug slows down stops and reverses direction

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

  13. 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

  14. The difference, the size of the force impulse and momentum, the small bug, the less force,impulse,change in momentum, the bigger the bug the more of each

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

  16. They stop

  17. What are some approximate numbers • Car mass 1500 kg • Car speed 60 mph 33m/s • Bug mass 1 g = .001 kg • Bug speed bug speed 10 mph 7 m/s

  18. 1500*33 + .001*-7 = ( 1500 + .001)v • 49500+ -.007 = 1500.001*v • 49499.993=1500.01*v • 32.99= v • So the car’s velocity changes from 33 to 32.99, while the bug changes from -1 to 32.99
