Energy Types and Conservation

Study Notes

Energy

Types of Energy

Electrical Energy: Energy associated with the movement of charged particles, such as electrons. It is a form of kinetic energy that is transferred through wires.
Thermal Energy: Energy of the motion of particles in a substance, resulting in heat. It is a form of kinetic energy that is transferred through conduction, convection, and radiation.
Kinetic Energy: Energy of motion, associated with an object's velocity. It is the energy of an object in motion.
Potential Energy: Energy of position or stored energy, associated with an object's potential to do work. It is the energy an object has due to its position or configuration.

Conservation of Energy

The law of Conservation of Energy states that energy cannot be created or destroyed, only converted from one form to another.
The total energy of a closed system remains constant over time, but the form of energy can change.
Energy can be converted from one form to another, but the total energy remains the same.
Examples of energy conversion:
- Electrical energy → Kinetic energy (e.g., electric motor)
- Thermal energy → Kinetic energy (e.g., steam engine)
- Potential energy → Kinetic energy (e.g., falling object)

Note: These notes provide a concise overview of the different types of energy and the concept of energy conservation. They are intended to serve as a starting point for further study and exploration of these topics.
