Work and Energy have the same unit because they are intimately related by the Work-Energy Theorem. This states that the Work done on an object moving from point A to point B is the difference in the Kinetic Energy it has at the two points. In simplified form it says that in order to do Work, you must use Energy; you can never do Work without using Energy, and so for convenience we give them the same unit. You didn't ask about Heat, but it really ought to be mentioned here, too; when you use Energy to do Work, some of the Energy usually gets converted to Heat by friction, so we can and do also use the same unit for Heat. Work and Energy and Heat are not the same thing, but they are inextricably related. By extension, the Theorem lets us define forms of Energy other than Kinetic Energy which enable us to do Work: Chemical Energy, Electrical Energy, Nuclear Energy, Gravitational Energy, etc. The SI unit of work or energy is Newton-meter (Nm). Another name for it is Joule (J). 1 joule is defined as the work done when a force of one newton acts over one metre of distance. 1 joule is also the amount of heat dissipated when a current of 1 ampere passes through a resistor of 1 ohm for 1 second (or 1 watt-second).

# Why are units of work and energy the same?

Work and Energy are analogous to Debt and Payment. If you owe me \$1, you should pay me \$1 to cancel your debt.. If work requires 1 J, then you must have the energy of 1 J to

# Why is energy measured in the same unit as work?

Because energy and work have the same dimensions: energy is the ability to do work and work is the expenditure of energy. The SI unit is the joule.

# What is the metric unit of work and energy?

Joule- a metric unit of work and energy

foot-pound

# Why is the joule a unit of energy and a unit of work?

Because energy and work have the same 'dimensions', which is the scientist's way of saying they both have the same make-up of the basic units, which are length, mass, and time

Volts and watts.

# Why are energy and work measured in same units?

Energy and work have the same units because......we say energy is the ability to do work....work is the energy transferred from a body to another.....the donor of energy is sa

momentum

# Why unit of heat is the same with energy?

Heat is a energy form.So unit of heat is the same as energy

# Why does work have the same unit as energy?

because work is a transformation of energy. If there is some loss of energy in a process then same amount of work will be created. For this reason the unit of work and energy

Yes.

# What is the SI unit or work and energy?

The Joule is the SI unit of energy or work. 1 Joule = (1 Newton)*(1 meter) or 1 kg*m 2 /s 2

# Why is the SI unit of work same as the SI unit of energy?

Consider "work" as a "change in energy" or "transfer of energy". It makes sense to use energy units for work.

# What is a metric unit of work and energy?

The derived SI unit of energy, and work is the joule. One joule is the energy used, or the work done, in applying a force of one newton through a distance of one metre; als
In Energy

# Why do energy and work have the same units?

They are closely related. You can think of work as the transfer of energy.
In Physics

# Are work and energy measured in the same units?

Yes. joule is that one
In Science

# What is the unit label for energy and work?

The SI unit of energy is the Joule .
