Kinematics

Describe motion before you explain it. Position, velocity, acceleration, and the paths projectiles actually take.

1. 1Position, velocity, accelerationMotion is a story told with derivatives. Engineers read it on graphs.12 min
2. 2Constant accelerationFour equations. They only hold when a is constant. That is most of freshman physics.14 min
3. 3ProjectilesBenchTwo independent motions sharing a clock. The range equation is a special case, not a religion.16 min
