There are different forms of energy depending on the source they come from.
Wind energy from wind.
Solar energy from the sun.
Chemical energy from biomass and petroleum products.
Electrical energy comes from electric cells or batteries, hydropower, wind power. Solar power and geothermal.
Thermal or heat energy from hot objects.
Mechanical energy from moving objects.
Kinetic and Potential Energy.
Forms of energy used in daily activities are either kinetic or potential.
Some are potential or kinetic depending on the activity being done.
1. Mechanical energy can be either potential or kinetic.
2. Electrical energy is kinetic.
3. Heat energy can be either potential or kinetic.
4. Chemical energy is potential.
5. Wind energy is kinetic.
6. Sound energy is kinetic.
7. Light energy is kinetic.
Uses of different forms of energy.
