Energy Stores and Transfers
This page focuses on different types of energy stores and how energy is transferred between them, providing essential information for understanding energy stores and transfers in science GCSE.
Types of Energy Stores The page lists and explains various energy stores:
- Thermal Energy Store
Definition: Thermal energy is stored in all objects, with higher temperatures indicating more stored energy.
- Kinetic Energy Store
Vocabulary: Kinetic energy is associated with movement.
- Chemical Energy Store
Example: Food and fuel are examples of chemical energy stores that release energy through chemical reactions.
- Gravitational Potential Energy Store
Definition: This is the energy stored in objects within a gravitational field, capable of being released when the object falls.
- Elastic Potential Energy Store
Example: Stretched springs store elastic potential energy.
- Electrostatic Energy Store
Definition: Energy stored in electric charges that attract or repel each other.
- Magnetic Energy Store
Example: Magnets that attract or repel each other store magnetic energy.
Energy Transfers Between Stores The page illustrates several examples of energy transfers:
- Dropping an Object
Highlight: Energy transfers from gravitational potential store to kinetic store.
- Burning Fuel
Example: Chemical energy store in fuel transfers to thermal energy store in surroundings.
- Releasing a Stretched Object
Highlight: Elastic potential energy store transfers to kinetic energy store.
- Using a Circuit to Move a Motor
Example: Chemical energy store in a battery transfers to kinetic energy store in the motor and thermal energy store in the surroundings.
Highlight: Understanding these energy stores and transfers examples is crucial for GCSE Physics and provides a foundation for more complex energy concepts.
