unit of measurement for work

The heat changes are measured in calories (cal), kilo calories (kcal), joules (J) or kilojoules (kJ). These are related as: 1 cal = 4.184J 1 kcal = 4.184kJ The S.I. unit of heat is joule or kilojoule Work is measured in terms of ergs or joules. I Joule = 10 ..

Work and Measurement of Work - Let us now discuss the conditions to be satisfied for work to be done. From the above examples, it is clear that work is said to be done when a force acts on an object and the point of application of the force moves in..

Work and Measurement of Work - Work is said to be done when a force acts on an object and the point of application of the force moves in the direction of force. Conditions to be satisfied for work to be done: Some force must act on the object The po..

When pure and dry H 2 gas is passed through the inlet tube, a part of the gas gets adsorbed and the excess bubbles out through the perforations. Between the H 2 gas absorbed on the surface of the metal and H + of the solution, an equilibrium is established and an electrical double layer of oppo..

Measurements - Everything that we use in our daily life is ultimately governed by principles of physics. All gadgets we use everyday at home, bicycles and cars, all different types of machinery and instruments, work on principles of physics. Hence to understand even the elementa..

One joule is the work done, when the point of application of a force of one Newton moves through a distance of one meter in the direction of forc..

SI Unit of Work - W = F x s SI unit of F is N and that of s is m [N=Newton] 1Nm is defined as 1 joule. i.e., 1 joule = 1..

Power is denoted by the letter 'P'. SI unit of power SI unit of work is joule and time is second. Therefore, SI unit of power is joule/second. 1 joule/second = 1 w..
