Energy Stores and Transfers
Revision Monkey・2 minutes read
Various types of energy stores exist, from chemical and thermal to kinetic and potential energy, with energy transfer following the law of conservation of energy. Wasted energy is transferred to the surroundings as heat, while energy can also be transferred through electrical, sound, and light means.
Insights
- Energy can exist in various forms like chemical, thermal, kinetic, gravitational potential, and elastic potential energy, each stored differently in objects.
- The law of conservation of energy dictates that energy can be transferred between these stores, ensuring the total energy before any transfer equals the total energy after, with wasted energy often manifesting as heat and transferring to the surroundings.

Energy Stores and Transfers: A Summary
- Different types of energy stores include chemical energy stored in food and fuels, thermal energy in hot objects, kinetic energy in moving objects, gravitational potential energy based on an object's position in a gravitational field, and elastic potential energy in compressed objects like springs or stretched items.
- Energy can be transferred between these stores, following the law of conservation of energy, where total energy before must equal total energy after. Wasted energy, such as heat from electrical equipment, is transferred to the surroundings, heating them up, while energy can also be transferred through electrical, sound, and light means.
