Force Makes the World Move! | Science Trek

A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. Sir Isaac Newton developed his laws of motion to explain how these forces act. What are these laws? And why do roller coasters and bumper cars illustrate Newton's laws? Learn all about force and motion and how force makes the world move on this episode of Science Trek!
