The joule is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).

WebbFor solids and liquids. cp = cv (1) The specific heat represents the amount of energy required to raise 1 kg of substance by 1oC (or 1 K), and can be thought of as the ability to absorb heat. The SI units of specific heats are J/kgK (kJ/kgoC). Water has a large specific heat of 4.19 kJ/kgoC compared to many other fluids and materials. The SI unit of work is the joule (J), named after the 19th-century English physicist James Prescott Joule, which is defined as the work required to exert a force of one newton through a displacement of one metre. The dimensionally equivalent newton-metre (N⋅m) is sometimes used as the measuring unit for work, … Visa mer In physics, 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 … Visa mer The work W done by a constant force of magnitude F on a point that moves a displacement s in a straight line in the direction of the force is the product For example, if a force of 10 newtons (F = 10 N) acts along a point that travels 2 metres (s = 2 m), … Visa mer The scalar product of a force F and the velocity v of its point of application defines the power input to a system at an instant of time. Integration of this power over the trajectory of the point of application, C = x(t), defines the work input to the system by the force. Visa mer The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include Visa mer Constraint forces determine the object's displacement in the system, limiting it within a range. For example, in the case of a Visa mer For moving objects, the quantity of work/time (power) is integrated along the trajectory of the point of application of the force. Thus, at any … Visa mer The principle of work and kinetic energy (also known as the work–energy principle) states that the work done by all forces acting on a particle (the work of the resultant force) … Visa mer
