Types of Energy - complete the chart


Energy is due to position or movement of an object - Kinetic and Potential

Forms of energy
What is it?
Example?
Kinetic energy
Energy in movement
Wind,water and electricity
Mechanical energy
Makes things move by workable moving part or parts
Wind up toy, scissors
Thermal energy
different forms such as chemical energy, electrical energy, heat
Fire,
Magnetic energy
Energy from attraction of objects made of iron
resonance imaging, or MRI, machine,

Electrical energy
An example:Lightning. Electrical charges moving through a wire or electricity. Static electricity.
A charged wire is called current, or more commonly, electricity.
Potential energy
Stored Energy
chemical,and nuclear energy
Gravitational energy
Energy stored in objects held above the earth’s surface
It is associated with gravity or gravitational force.
Elastic energy
Elastic energy occurs when objects are compressed and stretched, or generally deformed in any manner.
Slingshot,
Chemical energy
stored in the bonds of chemical compounds (atoms and molecules)
Batteries, biomass, petroleum, natural gas,
Nuclear energy
The energy released during nuclear fission or fusion especially when used to generate energy.
Nuclear power plant - provides electricity
