WebMar 7, 2024 · A joule is equal to the kinetic energy of a kilogram mass moving at the speed of one meter per second (one joule is a kg⋅m 2 ⋅s −2 ). Alternatively, it is the amount of work done on an object when a force of one newton acts in the direction of the object's motion over a distance of one meter (1 joule equal 1 newton meter or N⋅m). WebThe amount of work done by power of 1 kW in 1 hour is called kilowatt hour. For example, to calculate the work done in 1 hour at a rate of 1 kilowatt, we use the power equation. = Rearrange the equation to solve for work. To Calculate the work (W) done: = P = 1 kW or P = 1000 W = 1 hr or = 3,600 s W = P or W = P = (1 kW) (1 h) = (1,000 W) (3,600 s)

Joule Definition & Formula Britannica

WebExactly 1 Joules per second equal one Watt. This comes from the definition of the Watt, which is a unit of power used to quantify the rate of energy transfer. In the International System of Units (SI) it is defined as a derived unit of 1 Joule per second [1] with a symbol W. The formula for calculating Power in Watts (W) is: P(W) = E(J) / t(s) WebThe meaning of work in thermodynamics, and how to calculate work done by the compression or expansion of a gas Key Points: Work is the energy required to move something against a force. The energy of a system can change due to work and other forms of energy transfer such as heat. Gases do expansion or compression work following the … The terms power and energy are closely related but distinct physical quantities. Power is the rate at which energy is generated or consumed and hence is measured in units (e.g. watts) that represent energy per unit time. For example, when a light bulb with a power rating of 100W is turned on for one hour, the energy used is 100 watt hours (W·h), 0.1 kilowatt hour, or 360 kJ. This same amount of energy would ligh… symbicort without insurance
