Newton's Third Law of Motion

This section introduces Newton's Third Law of Motion - If a force is exerted by one object to another object, another force is simultaneously exerted by the second object to the first object with equal strength and opposite direction.

Newton's Third Law of Motion - If a force is exerted by one object to another object, another force is simultaneously exerted by the second object to the first object with equal strength and opposite direction.

For example, when you push the water backward with a force, F, with a paddle, the water will push you forward with an opposite force, F' = -F. Under the force F, some water will move backward. And under the force F', you and your canoe will move forward.
