Newtons+Third+Law

Newton's first law involves mass, acceleration, inertia, and force. He says that **"Every action has an equal and opposite reaction."** Whenever something exerts force on something else, //the second one simultaneously// exerts force on //the first one// with the same magnitude in the opposite direction. For example: Conan the Warrior ambushes a man on horse with a giant battle axe. He slices through the man's intestines, but receives a small push from the hit. His heavy, giant battle axe was full of mass and inertia, and he swung it with fierce acceleration and force. The force he exerted give him the same magnitude back to him.

Or, for example, say a man walks across a frozen lake. and the ice supports his weight. Now say a really fat man walks across the same ice, and it cracks and he falls into the water. The reason that the first man was able to cross safely was that the ice exerted the same force upward on him as the man's weight did on the ice. In this case, the man's weight was pressing down, and the ice was pressing up with the same force, so he says on top, the fat man's weight on the other hand, exerts a greater force on the ice than the ice is able to give back. This creates an inequality in the forces and thus the man falls through the ice.

Another example is a gun's recoil. When a gun is fired and the bullet goes flying out the barrel, the gun kicks back with the same force as the bullet leaving it. -Drew

Newton’s Third Law: If two bodies interact, the force exerted on body 1 by body 2 is    equal to and opposite the force exerted on body 2 by body 1. Tasha

How is this an example of Newton's thrid law? media type="file" key="039-corvette-crash.wmv"

When the car hits the back of the semi, the semi returns the force equally which nullifies the car's acceleration. Also the carloses control because it exceeds the limit of friction possible between the wheels and the grund. Which equals BOOM! -longboardlarry
