Question
Identify 4 forms of energy and give an example of each
Solution
-
Mechanical Energy: This is the energy that is possessed by an object due to its motion or due to its position. An example of mechanical energy is the kinetic energy of a moving car.
-
Chemical Energy: This is the energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by-product (exothermic reaction). An example of chemical energy is the energy stored in gasoline. When gasoline is burned in a car engine, it is converted into mechanical energy that moves the car.
-
Electrical Energy: This is the energy derived from electric potential energy or kinetic energy. An example of electrical energy is the energy used to power your computer or smartphone.
-
Thermal Energy: This is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated. An example of thermal energy is the heat from a hot cup of coffee.
