Newton’s Third Law of Motion


Sir Isaac Newton, an English scientist born in 1642, discovered three important principles of physics that describe how things move. Consequently, the principles bear his name, Newton’s First, Second, and Third Laws of Motion. Today’s experiment demonstrates Newton’s Third Law of Motion. It says that for every action there is an equal and opposite re-action. Basically, if an object is pushed, that object will push back in the opposite direction, equally hard.

Newton’s Laws of Motion: The Science Behind How Things Move

Newton’s Laws of Motion explain force and motion, or why things move the way they do. They are great concepts to explore by doing a science experiment. These are especially good science project ideas for kids who like to move! The concepts can often be explained using sports equipment or by understanding how amusement park rides work. These books offer ideas for physics experiments that demonstrate force and motion and the laws that govern them. Some of them provide the background information needed for the report that is often required to go with projects for the science fair.
