Energy Transfers

• Heating

  • Heating an object transfers energy to its internal store (the sum of the energy in the kinetic and chemical stores of its p
• Waves

  • Light and other types of waves can transfer energy from one object to another.
• Electrical work

  • An electrical current transfers energy from one object to another, such as a battery powering a torch.
• Mechanical work

  • Energy transferred from one object to another via a force is an example of mechanical work.
  • When an object falls from a building, the weight does mechanical work to transfer energy from the gravitational potential store to the kinetic store.
  • When you push a wheelchair, energy is transferred to the kinetic store of the wheelchair.
