How can physics be about movement if nothing wants to move? Ah, but forces in the universe make things move and stop moving. But at heart, the first rule of physics says: ""Things like to keep doing what they're already doing.""

This program introduces the kilogram as a way to measure the mass of an object, and proves that small things can me more massive than large things.
Expert ball-handling proves force varies with mass and speed.
Force varies with mass and rate of change of speed. It's much easier to stop a slow-moving cannonball than a rapid tennis ball.
It takes only a few seconds for something to accelerate to a max speed. This is demonstrated with a vintage locomotive.
What is gravity? Through the fictional story of Newton's apple, we learn about gravity and shed some light on weight.
Physics has to be specific in distinguishing weight from mass. This is why physicists measure weight in newtons.
How much work are you doing? Whatever the force you apply is measured in newton meters–or joules, after James P. Joule.
The physics of billiard balls begins the first of two programs on energy itself.
David and Goliath characters demonstrate how potential energy differs from kinetic energy.
