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).

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 satisfy the work requirment, or the job is NOT DONE.
Well its kinda like a hole calss bout in a hand full of m&m and the teatcher had a big buckit and told you to put all your m&ms in it and then he grabe more and re-gave them out. That's like the energy they kinda mix it togather and then send it out all over.
I hope that ansered your qustion.
I learned that today in sciene. and that how he explaned it.
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. In fact energy can be defined as the capacity for doing work, which is potential energy, and when work is done energy is expended.
When a power plant generates say 1000 MegaWatts, this is called Energy, and it is sent out to the grid. At the same time many different loads are using this energy, some for electric motors, some for heating, others in various industrial processes, some to run computers, and so on. These loads are all doing work, and consuming energy in doing so. 1000 MW is 109 Watts, and this means 109 Joules per second, so that is the work being done every second by all these various loads combined.
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 said to have done work upon the acceptor...
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.
The Joule, commonly abbreviated J, is the SI unit for work and energy. 1 J = k-m2/s2
Consider "work" as a "change in energy" or "transfer of energy". It makes sense to use energy units for work.
Yes. joule is that one
Yes, work and energy have the same units. In the SI system, both are measured in Joules.
Energy and work are the samething.their is no difference between the two of them.All have the same unit that is Joules.Energy is the ability to do work and work is when a force acts on abody and the body moves to the direction of the force.In other ways we can say work is energy transfer.For examplewhen we lift a body to a height h We increase its Pontential enrgy(P.E).However we have to know that for the increase in P.E a person had to carry the body to the height by giving in a force.Work=Force* DistanceThis means work was done to transfer the initial P.E to the final P.E.This proves that work and energy are not different.Further AnswerAnother way of defining work is to say that work is done whenever one form of energy is changed into another form. For example, an electric motor is doing work when it changes electrical energy into kinetic energy.
Joules (J) This is because work is energy transferred, and energy is measured in Joules.
The concept called "work" in physics is measured in the same units as energy. The international (SI) unit is the joule.
They are closely related. You can think of work as the transfer of energy.
energy
Yes, work and energy have the same units. In the SI system, both are measured in Joules.
Work is simply the transfer of energy. Both work and energy are measured in the same units, for example, Joules.
Energy is the ability to do work . It is measured in Joules.
Work is transfer of energy, so it has the same units as energy. Power is the amount of energy transferred per unit time, so it does not have the same units of energy. Rather, its units are energy/time.

Yes. Work is just one particular method of moving energy, they both have the same physical dimensions, and they're both measured and described with the same units.
The concept called "work" in physics is measured in the same units as energy. The international (SI) unit is the joule.
In very general terms, power is work (or energy, same units) per unit time. In SI units, power is measured in watts, which are joules per second.
Yes.
They are closely related. You can think of work as the transfer of energy.
