Lesson 14 - Sources of Energy-Class 10 Science Notes
Sources of Energy Energy:- In physics, energy is the capacity for doing work. Or Energy is defined as the ability to do work. Types of Energy:- Energy comes in various forms- 1. Kinetic energy 2. Potential energy 3 . Thermal energy 4. Electrical energy 5. Chemical energy 6. Light energy 7. Sound energy 8. Wave energy 9. Gravitational energy 10. Wind energy 1. Kinetic energy:- Kinetic energy is the energy of motion of a body. Example- Child swinging on a swing. 2. Potential energy:- Potential energy is the energy of object’s position. Example- Energy of ball at highest point while throwing. 3. Thermal energy:- Thermal energy or heat energy reflects the temperature difference between to systems. Example:- A cup of tea has thermal energy. 4. Electrical energy:- Electrical energy is the movement of electrons. Example- Electricity used in homes. 5. Chemical energy:- Chemical energy is the energy stored in the bonds o
