Advanced Placement Physics C: Mechanics with calculus-based physics principles.
Work, energy, and power are all about how forces transfer energy and cause motion.
Work is done when a force moves an object: \( W = \int \vec{F} \cdot d\vec{s} \).
Energy cannot be created or destroyed—just transformed from one form to another.
Power is the rate at which work is done: \( P = \frac{dW}{dt} \).
This section helps explain why lifting a backpack slowly uses less power than sprinting up stairs with it!
A roller coaster converts potential energy at the top of a hill into kinetic energy as it speeds downward.
Cyclists increase their power output to climb steep hills faster.
Work and energy describe how forces move and change objects, while power shows how quickly this happens.
