Work Power And Energy Definition In Hindi

Exergy and energy both have units of joules the internal energy of a system is always.

Work power and energy definition in hindi.

This lecture explains the basics of work and power and also talks about energy and its units. Exergy is a combination property of a system and its environment because it depends on the state of both the system and environment. Energy versus power comparison chart. The exergy of a system in equilibrium with the environment is zero.

Power is the rate at which work is done or energy is transmitted. 16 lessons 3 h 3 m. Because energy is the capacity to do work we measure energy and work in the same units n m or joules. Work power and energy in hindi lesson 4 of 16 598 upvotes 10 42 mins.

Constraint forces edit constraint forces limit the movement of components in a system such as constraining an object to a surface in the case of a slope plus gravity the object is stuck to the slope when attached to a taut string it cannot move. Energy is power integrated over time. The work energy principles discussed here are identical to electric work energy principles. Work done is generally referred in relation to the force applied while energy is used in reference to other factors such as heat.

Joules watt seconds or joule newton meter. Power p is the rate of energy generation or absorption over time p e t power s si unit of measurement is the watt representing the generation or absorption of energy at the rate of 1 joule sec. Work and energy can be considered as two sides of the same coin. In this article we will learn all about the concept of work power and energy.

Exergy is neither a thermodynamic property of matter nor a thermodynamic potential of a system. Work whenever a force acting on a body produces a change in the position of the body work is said to be done by the force. Power s unit of measurement in the. Notes for work energy and power chapter of class 11 physics.

Energy is the capacity to do work.
