Various scenes illustrate Newton’s laws of motion, including a pool cue striking a ball, a bullet being fired, a baseball being thrown, and a bowling ball rolling down a lane.

I want to talk about forces. So, what are forces? Well forces cause things to change, and a beautiful example of that is Newton's first law of motion. It says that things stay still or carry on ...

Newton's first law can also be used to explain the movement of objects travelling with non-uniform motion. This includes situations when the speed changes, the direction changes, or both change.
