## FAQs on Mindmap: Work, Power and Energy - Physics Class 11 - NEET

 1. What is work in physics?
Ans. In physics, work is defined as the transfer of energy that occurs when a force is applied to an object and the object is displaced in the direction of the force. It can be calculated by multiplying the force exerted on an object by the distance it moves in the direction of the force.
 2. How is power related to work and time?
Ans. Power is the rate at which work is done or energy is transferred. It is calculated by dividing the work done or energy transferred by the time taken to do the work or transfer the energy. Mathematically, power (P) = work (W) / time (t).
 3. What are the different forms of energy?
Ans. There are several forms of energy, including kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat energy), chemical energy (energy stored in chemical bonds), electrical energy (energy associated with the flow of electric charge), and nuclear energy (energy stored in the nucleus of an atom).
 4. How is energy converted from one form to another?
Ans. Energy can be converted from one form to another through various processes. For example, a moving car converts its kinetic energy into thermal energy (due to friction with the road), sound energy (due to the engine noise), and potential energy (when it climbs a hill). Energy conversion can occur through mechanical work, heat transfer, chemical reactions, or electromagnetic processes.
 5. What is the principle of conservation of energy?
Ans. The principle of conservation of energy states that energy cannot be created or destroyed, but it can only be transformed from one form to another or transferred between objects. In other words, the total amount of energy in a closed system remains constant. This principle is based on the law of conservation of energy, which is a fundamental concept in physics.
