3.3 – Potential Energy
AP Physics 1 – Unit 3.3: Potential Energy
This AI-generated video lesson reviews key ideas from Unit 3.3, including:
• A system composed of two or more objects has potential energy if the objects within that system only interact with each other through conservative forces.
• Potential energy is a scalar quantity associated with the position of objects within a system.
• Because the gravitational field near the surface of a planet is nearly constant, the change in gravitational potential energy in a system consisting of an object with mass m and a planet with gravitational field of magnitude g when the object is near the surface of the planet may be approximated by the equation ∆Ug = mg∆y.
