Bend an object's ends past each other - eg when an archer pulls an arrow back against a bow. Pull an object's ends apart - eg when a rubber band is stretched. Push an object's ends together - eg when ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...
