Push one way and you get pushed back the other. Every action has an equal and opposite reaction, just like a launching rocket.

Simple Camera

A lens gathers light and forms a clear picture, exactly like the camera inside your own eye. See how images are made.

Mass and Inertia

Heavy things are hard to start moving and hard to stop. That stubbornness is called inertia.
