6 Unforgivable Sins Of Goo

Work Definition, Meaning & Synonyms

Work in Physics is defined as the transfer of energy when an object moves from one place to another. We tend to use the word ‘work’ to convey our efforts. Our parents work hard to give us a good life. Some people do a lot of workouts to stay fit.

More examples Sidney ruthlessly Worked his way up from the position of junior clerk to chairman of the company. It's a common-or-garden washing machine with just the basic functions, but it works perfectly well. Dust particles must have got into the motor, which is why it isn't working properly. However they wanted to maximize what they were bringing to the company.

No work, as understood in this context, is done unless the object is displaced in some way and there is a component of the force along the path over which the object is moved. Holding a heavy object stationary does not transfer energy to it, because there is no displacement. Exertion or effort directed to produce or accomplish something; labor; toil. The result of exertion, labor, or activity; a deed, performance, or product. N., adj., v. worked (Archaic except in some senses, esp. 35,37,40 ) wrought; working.

Work transfers energy from one place to another or one form to another. For example, in a pulley system like the Atwood machine, the internal forces on the rope and at the supporting pulley do no work on the system. Therefore, work need only be computed for the gravitational forces acting on the bodies.

In its simplest form, for a constant force aligned with the direction of motion, it equals the product of the force strength and the distance traveled. A force is said to do positive work if when applied it has a component in the direction of the displacement of the point of application. A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force. The derivation of the work–energy principle begins with Newton’s second law of motion and the resultant force on a particle.

Ans.Work is the product of force and displacement in the direction of the force. For uniform circular motion, the force acts perpendicular to the direction of the motion, so the force never does any work upon the object. If a force acting on a body has a component in the direction opposite to displacement, then the work done by the force is negative.

Hence, the work done by the frictional force on the body is negative. Similarly, an object experiences a zero force when the displacement angle is perpendicular to the direction of the force. Consider an example of a coolie lifting a mass on his head moving at an angle of 90˚ with respect to the force of gravity. Here, the work done by gravity on the object is zero. The SI unit of work is thejoule , which is defined as the work done by a force of 1 Newton in moving an object through a distance of 1 meter in the direction of the force. Work is the product of the component of the force in the direction of the displacement and the magnitude of this displacement.

The words labor and work are synonyms, but do differ in nuance. Specifically, labor applies to physical or intellectual work involving great and often strenuous exertion. ˈworkout noun a period of hard physical exercise for the purpose of keeping fit etc. The transfer of energy, as measured by the scalar product of a force and the distance through which it acts. Work may imply activity of body, of mind, of a machine, or of a natural force. Make it easier to focus on important work by eliminating manual processes.

They are expected to work twelve hours a day → On attend d'eux qu'ils travaillent douze heures par jour. Force multiplied by distance; work is measured in joules. If you have work, you have a job which you are paid to do. You use the progressive -ing form of work to talk about a temporary job, but simple forms to talk about a permanent job. For example, if you say 'I'm working in London', this suggests that the situation is temporary and you may soon move.
