Kinetic and Potential Energy Concepts

Mr. Clausen explains potential and kinetic energy calculations in a video tutorial. He covers the concepts of potential energy, which depends on mass, height, and gravity, and kinetic energy, which depends on mass and velocity. The video includes sample problems and a review of related concepts like momentum and power. Students are encouraged to complete practice problems and check their answers in the daily notes folder.

What are the three factors that potential energy depends on?

• Mass, velocity, and time

• Mass, height, and velocity
