PHYSICS: Energy transfer

HideShow resource information

How is energy transferred?

  • By heating
  • Mechanically
  • Electrically
  • By radiation

By heating

Some objects are hotter than others.

Energy is transferred from the hotter object to the cooler one, the difference in temperature between them decreases.

Mechanically

Energy can be transferred through mechanically through the movement of the parts in machines, and when the motion or posiiton of an object changes.

Sound waves and seismic waves (produced by earth quakes) are mechanical that transfer energy through materials and from place to place.

Electrically

Energy
