Grade 11 Physics Concepts: Third Law
Here, we start off today's blog post with some head on collision action!
And now, onto Newton's Third Law of Motion!!
The Third Law of Motion states, “For every action force, there exists a simultaneous reaction force that is equal in magnitude but opposite in direction.”
For example, a passenger slamming into the car means, the car will “hit” the passenger back with the same force. Or, a car hitting a wall will receive an equal reaction force.
The following image is an example of This third law, happening to some unfortunate people at home....
And finally, a video to finish things off; from the show..... Mythbusters!! It's always fun watching them do wack experiments and break things. In this short clip, they crash 4 cars. Amazing. (5minutes 50seconds)
Smol Video Summary:
The Mythbusters are testing out physics third law with 2 cars of the same length and weight. First, they crash two similar cars at different speeds against a wall. The one at a higher speed was more crumpled than the car at the slower speed. The second and final experiment was one with a head on collision. They took 2 similar cars, and smashed them together at the same speed as the earlier slower speed. The result of the two cars showed that the damage factor was the same as the time they smashed the car into a wall. It was confirmed that Newton’s third law, that every action force has an equal reaction force was indeed correct with this practical test.
