The joule ( jawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m).

20 joules is equivalent to 14.75 foot lbs. The US and the UK use foot pounds as their unit of measurement. Most other countries use joules as their unit of measurement.

Heat is a form of energy. It is measured in Joules. ... The temperature of an object relates to both the kinetic energy of its particles and the number of particles. Temperature is the average kinetic energy of the particles in a substance.

Defined in these scientific terms, 1 volt is equal to 1 joule of electric potential energy per (divided by) 1 coulomb of charge. Thus, a 9-volt battery releases 9 joules of energy for every coulomb of charge moved through a circuit.

A volt is a unit of measure assigned to the electrical potential or voltage across a conductor. However a joule is a unit of energy or work done, to move an electric charge through an electric potential. ... Whereas, voltage is the speed at which the current is moving along the line.

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.

Units. The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second.

Joule/meter. The joule per meter is a unit of force and equivalent to newton (1 joule per meter = 1 newton).

The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%. Wout = the work or energy produced by a process. Units are Joules (J).

Heat is the transfer of thermal energy from a system to its surroundings or from one object to another as a result of a difference in temperature. Heat is measured in joules (J). This is because heat is a transfer of energy. ... Temperature is a measure of the average kinetic energy of the particles in an object or system.

Watt, unit of power in the International System of Units (SI) equal to one joule of work performed per second, or to 1/746 horsepower. An equivalent is the power dissipated in an electrical conductor carrying one ampere current between points at one volt potential difference.

The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). ... Therefore, one joule equals one newton•meter.

Power in general is defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.

1 Watt-hour is equal to 3600 Joules (3.6kJ). One Kilowatt-Hour is the same as 1,000 Watt-hours and is the most common unit used in electrical energy consumption.

The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). ... The amount of energy delivered by a one watt source of power in one second is one Joule.

Joule is unit of energy as well as work. ... In other words, energy and work have the same units.) On the other hand, Watt is the unit of 'power', which is energy per unit time (Joules per second). So the amount of energy is measured in Joules, while the rate of the flow of this energy is measured in Watts.
