In equation form: work (joules) = force (newtons) x distance (meters), … One joule is defined as the amount of work done when a force of one newton is exerted through a distance of one meter.
Moreover, What is joules MJ?
Thus, a kiloJoule (kJ) is 1000 Joules and a megaJoule (MJ) is 1,000,000 Joules.
What can 1 joule of energy do?
One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.
Also Which unit is Watt? Watts (W) and Kilowatts (kW):
Watts are the SI unit of power. Kilowatts are equivalent to 1,000 Watts and are the most frequently used unit of electrical power. 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.
What does joule’s law state?
noun Physics. the principle that the rate of production of heat by a constant direct current is directly proportional to the resistance of the circuit and to the square of the current. the principle that the internal energy of a given mass of an ideal gas is solely a function of its temperature.
