What is a Newton meter? A unit of energy also known as a Joule. When a force of 1 Newton is applied on an object for a distance of 1 meter then 1 Joule of energy is used. It is the result of a vector calculation involving the meter (a unit of length in the SI system) and the Newton (the unit of force in the SI system). A unit of torque.

- A Joule is a unit of energy. 1 watt is 1 Joule per second. Therefore 1 kilowatt is 1 kilojoule per second. The prefix 'kilo' just means 'times one thousand'. The Joule is defined as the energy required to move a mass of 1 kg by 1 meter against a force of 1 Newton. This is in the SI system of units.

What is a Joule? Let’s go back to the apple example mentioned earlier to elaborate. An apple is a favorite example to illustrate a one joule of work when using the definition given earlier (i.e., the amount of work done ….) because an apple weighs approximately one Newton. Thus, you’d have to exert a one Newton upward force to counteract its one Newton weight.

What is the difference between a joule of work and a joule of energy? Best Answer: There is no difference. Technically, a Joule is a unit of energy, and work is a type of energy. In scientific terms, work is done when a force causes an object to move in the direction of the force. Work is a specific type of energy. equal.work and energy are equivalent.

Work: Definition, Characteristics, and Examples The joule is a combination of both of the components on the right side of our work equation: force and distance. Quite simply, a joule is a Newton-meter (N*m), and one joule of work is done when a force of 1 N is exerted over a distance of 1 m. This amount of work is on par with lifting an apple over your head.

How many joules are in a single coulomb? Watts is a unit of power that is equal to volts x amps x Power  Factor.   Answer    The watt is the SI unit for power.    Power is defined as 'the rate of d…oing work'. Since work is  measured in joules, the watt is equivalent to (a special name given  to) a joule per second.

How Many Joules Are in a Calorie? Full Answer. A calorie is a unit of energy that measures how much energy is needed to increase the temperature of a single gram of water. The primary measure of energy, however, is the joule, which is equal to one newton-meter. It is the standard unit of energy in both the imperial and metric system.

What is a Joule? This ability, when measured in joules, is equivalent to one joule. Meaning, when you release the apple, the force of gravity, which is simply just the weight of the body and equivalent to one Newton, would be able to perform one joule of work on it when the apple drops down from a height of one meter.

- Joules is the energy released by a small reference earthquake. The energy, can be obtained directly from the Gutenberg-Richter magnitude-energy relation, here expressed in units of Joules: log E = 1.5 R + 4.8 or equivalently: E = 101.5 R + 4.8. Joules; we can convert these units to equivalent tons of TNT.
