📖 1. Energy Stores

🔑 Key Concepts & Definitions

  • Magnetic energy store: The energy stored in magnetic fields, such as in magnets or electromagnets. This energy can be released when magnetic objects interact or move relative to each other.

  • Kinetic energy store: The energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has (AUTHOR (date): "Kinetic energy depends on mass and velocity").

  • Thermal energy store: The energy stored in the vibrations of particles within a substance, resulting in heat. It increases when an object heats up and decreases when it cools down.

  • Elastic potential energy store: The energy stored in stretched or compressed objects, such as springs or elastic bands. This energy is released when the object returns to its original shape.

  • Gravitational potential energy store: The energy stored in an object due to its position above the ground. The higher the object, the greater its gravitational potential energy (AUTHOR (date): "Energy stored as a result of an object's height above the ground").
