Energy Types and Conservation

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.
