Work is how much force it takes to move an object in the same direction as the force. Power is how long it takes you to do the work.

Heat vs work. Heat and work are two different ways of transferring energy from one system to another. ... Heat is the transfer of thermal energy between systems, while work is the transfer of mechanical energy between two systems.

Force vs. Power. ... Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element. Force and power can both be described and measured, but a force is an actual physical phenomenon, and power in itself is not.

As nouns the difference between work and labour is that work is (uncountable) labour, employment, occupation, job while labour is effort expended on a particular task; toil, work.

In physics, the term "work" has a specific meaning. Work, in physics, occurs when a force acts on an object to move it some distance from the start point (also called displacement). Work is calculated as the force times the distance.

Energy is the ability to do work. It powers every machine and is necessary for every activity.

There is a significant difference between work and energy. Work is the transferring of an amount of energy with the help of a force covering a particular distance through a direction. Energy is also referred to the force which works in a certain distance. These both can be termed as scalar units.

A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work. The link of a machine may transmit both power and motion, while the members of a structure transmit forces only.

Power Formula. Power is a rate at which work is done, or energy is used. It is equal to the amount of work done divided by the time it takes to do the work. The unit of power is the Watt (W), which is equal to a Joule per second (J/s).

Work done = Energy transferred. W = E. Power = Energy ÷ Time. P = E ÷ t.

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). ... A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.

In Physics, work is defined as the result of a force moving an object a certain distance. ... Displacement is the distance and direction an object is moved. Force and work are directly proportional to each other, while force and displacement are indirectly propotional. The equation showing the relationship is W= Fd.

The mechanical power is measured by the rate at which work is done. ... The unit Kw is an electrical as well as mechanical power unit. Though the basic concepts remain the same, the form of the governing equations in case of the mechanical power is different than that of electrical power.

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.

As verbs the difference between act and work is that act is to do something while work is to do a specific task by employing physical or mental powers.

With power and energy, power is units of energy divided by time. The same difference as distance and velocity. The units of power are watts, the units of energy are joules. A watt is one joule divided by one second.

Energy and power are closely related but are not the same physical quantity. Energy is the ability to cause change; power is the rate energy is moved, or used.
