Study Notes

Energy Overview

Energy is the capacity to do work or produce change in a system.
It exists in various forms, including kinetic, potential, thermal, chemical, and nuclear energy.

Types of Energy

Potential Energy: Associated with the relative position of an object, determined by its height and mass in a gravitational field.
Kinetic Energy: The energy of motion, dependent on the mass and speed of an object.

Temperature and Thermal Energy

Temperature: A quantitative measure of the average kinetic energy of particles in a substance, reflecting how hot or cold it is.
Thermal Energy: The total internal energy of a system due to the kinetic energy of its particles. It increases with temperature.

Energy Conversion

During energy conversion, energy changes from one form to another, but the total energy is conserved (according to the law of conservation of energy).
Examples include transforming potential energy into kinetic energy or converting electrical energy into thermal energy.
