1.1.1 Identifying Different Energy Stores

• An energy store is a reservoir where energy is held in a particular form
• Thermal energy is stored as heat in a substance.


  True
• Thermal energy stores are reservoirs where energy is stored in the form of heat.

  True
• Thermal energy stores can be increased by adding heat
• Match the kinetic energy store with its example:

  Moving car ↔️ Energy in a vehicle in motion

  Spinning top ↔️ Energy in the rotational motion of a toy

  Flowing water ↔️ Energy in moving water in a river

  Falling object ↔️ Energy in an object falling under gravity
• Nuclear energy is stored within the nucleus of an atom.


  True
• A kinetic energy store is a reservoir where energy is stored due to an object's motion


  True
• Kinetic energy increases with higher speed


  True
• Elastic potential energy is stored in an object when it is deformed


  True
• Chemical energy can be transferred to kinetic, thermal, or electrical stores
• Order the following energy stores from most to least common:

  1️⃣ Gravitational

  2️⃣ Kinetic

  3️⃣ Elastic

  4️⃣ Chemical

  5️⃣ Thermal
• A ball held above the ground is an example of gravitational potential energy
• Thermal energy is stored in the vibrations of atoms in solids

  True
• Match the thermal energy store with its example:

  Solids ↔️ Hot metal object

  Liquids ↔️ Hot water in a kettle

  Gases ↔️ Hot air in a room
• Elastic potential energy is stored when an object is compressed


  True

  True
• A potential energy store is a reservoir where energy is stored due to an object's position
• Elastic potential energy is stored when an object is stretched or compressed.


  True
• Match the chemical energy store with its example:

  Food ↔️ Eating a meal

  Fuels ↔️ Burning fuel in a car

  Batteries ↔️ Powering a flashlight
• Elastic potential energy is released when an object returns to its original shape.


  True
