Introduction to Force
Defining Force. Including its dimensions, demonstrations of force and mass affecting acceleration, showing that a force is an interaction between two objects and contact vs. field forces.
Professor Dave Explains
Dynamics: What are Forces?
What's a force? No, not THE force. That's from Star Wars. I'm talking about the forces in the universe that make things move. Yes, I know Yoda moved the X-Wing with The Force. Will you quit it? We are talking about the real universe...

Newton's Second Law of Motion: F = ma
One of the best things about Newton was the way that he showed how natural phenomena abide by rigid mathematical principles. So much so that we can use mathematical equations to calculate how objects will actually behave. This equation,...
