Energy and their types
Energy :- The ability do work is called energy.
Forms of energy in physical form:-
1. Mechanical energy
2. Electrical energy
3. Heat energy
4. Light Energy
5. Sound Energy
6. Chemical energy
7. Magnetic energy
Types of energy :-
1. Kinetic energy :- The energy generated due to motion in an object is called kinetic energy.
K. E. =1/2 mv^2 m=mass
= 1/2 × w/g × v^2 v= velocity g= gravitational acceleration
(w=mg)
2. Potential energy :-
T he energy generated due to the state or position of an object is called potential energy.
P. E= mgh h= height
Conservation of energy :- Energy can be changed from one form to another but it cannot be generated or destroyed, the result of energy in the universe is constant. This is called the principle of energy conservation.
