Inertia
Jan 1, 19805mHow 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.""
- S1E2
Mass
5mThis 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.
- S1E4
Acceleration (1)
5mForce varies with mass and rate of change of speed. It's much easier to stop a slow-moving cannonball than a rapid tennis ball.
- S1E5
Acceleration (2)
5mIt takes only a few seconds for something to accelerate to a max speed. This is demonstrated with a vintage locomotive.
- S1E6
Gravity
5mWhat is gravity? Through the fictional story of Newton's apple, we learn about gravity and shed some light on weight.
- S1E7
Weight vs. Mass
5mPhysics has to be specific in distinguishing weight from mass. This is why physicists measure weight in newtons.
- S1E8
Work
5mHow much work are you doing? Whatever the force you apply is measured in newton meters–or joules, after James P. Joule.
- S1E9
Kinetic Energy
5mThe physics of billiard balls begins the first of two programs on energy itself.
- S1E10
Potential Energy
5mDavid and Goliath characters demonstrate how potential energy differs from kinetic energy.
