Science Experiment: Newton's First Law of Motion


Physicists study matter - all of the "stuff" in the universe and how that "stuff" moves. One of the most famous physicists of all time was Sir Isaac Newton. Sir Isaac is most famous for explaining gravity, a concept we are so familiar with now it seems obvious to us. He is also famous for explaining how stuff moves, his Three Laws of Motion. Today we are going to look at Newton's First Law of Motion called Inertia.

Newton's First Law of Motion (Inertia): A still object will stay still unless a force pushes or pulls it. A moving object will stay moving unless a force pushes or pulls it.

Gravity and friction are forces that constantly push and pull the "stuff" on earth. So, when we roll a ball, it slowly comes to a stop. On the moon, where there is less gravity and friction, "stuff" floats, and keeps floating.

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. #indyplkids IndyPL_CarrieW
