In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.

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. Power is a scalar quantity.
4 cze 2021 · Work, Power and Energy is a very important concept in physics. Work done by all the forces is equal to the change in kinetic energy. In physics, work is related to the amount of energy transferred in or from a system by a force. It is a scalar-valued quantity with SI units of Joule. Work can be represented in a number of ways.
Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
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.
In physics, power (symbol: P) is how fast work is done or energy is given from one thing to another. In the SI system of measurement, power is measured in watts (symbol: W). It may take a certain amount of work to make a change in the world, such as lifting a heavy weight to a higher level.
The work-energy principle states that the work done on an object is equal to the change in its kinetic energy: W = Δ K {\displaystyle W=\Delta K} Potential energy
