Video - MythBusters - Crash Force
Mythbusters crew decided to revisit an old myth that was drawing the ire of the show's fans for quite some time. And it's sure to be an interesting topic to automotive enthusiasts.
When two cars collide, each traveling 50 miles per hour, does the resulting force equal one car hitting an immovable object at 100 miles per hour?
It seems like such simple physics, no? But don't forget Newton's third law. To quote the great Wikipedia of knowledge, "Whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction." Or, more simply, for every action there is an equal and opposite reaction.

 

Hey I liked the way you have explained.Specially the example you have used.I liked the video also which yo have shared.It was really great.

 

Hey that video was really great.thanks for sharing with us.Truly it was an awesome test.

 

It is much better to watch the video than try to explain the science.

 

This is so fascinating. love the video. I totally remember learning about Newton's laws back in my junior year of high school...bla. still..kind of interesting.
