Study Notes
Physics Overview
- Physics belongs to the natural sciences, focusing on the fundamental principles governing matter, energy, space, and time.
Definition of Force
- Force is an interaction that, when unopposed, changes the motion of an object. It is measured in newtons (N) and quantified by Newton's second law of motion.
Definition of Energy
- Energy is the capacity to perform work or generate heat, existing in various forms such as kinetic, potential, thermal, and chemical.
Definition of Potential Energy
- Potential energy is the stored energy of an object based on its position or configuration, capable of transforming into kinetic energy when the object is set in motion.
Maximum Potential Energy Points
- The two points of maximum potential energy occur at the highest elevation of a system, such as the peak of a hill or the top position of a pendulum swing.
