What is the difference between work done and energy?
Work done is a transfer of energy that occurs when a force is applied to move an object over a distance. Energy is the ability to do work and exists in different forms such as kinetic, potential, and thermal energy. Work done is the result of energy being transferred, while energy is the capacity for doing work.
Why is the unit of the amount of work done the same as the unit for energy?
The unit of work done is the joule (J), which is also the unit for energy. This is because work done is the transfer of energy from one system to another. So, the unit for work done being the same as the unit for energy reflects the close connection between the two in the context of physics.
What is difference in work done by fuel and work done by moving object?
work done by fuel is conversion of chemical energy into mechanical whereas work done by moving object is due to its displacement by the application of force. actually, both of them give same meaning.
Why do energy and work have the same units?
Energy and work have the same units (joules) because work is the transfer of energy from one form to another. When work is done on an object, energy is either transferred into or out of the object. This transfer of energy is what causes change in the object's state.
A spring is stretched - what is the work done by the stretching body?
The work done by the stretching body is equal to the difference in potential energy stored in the spring before and after it is stretched. This work is done against the restoring force of the spring.
Which can do more work-a joule of heat energy or a joule of sound energy?
Joule is a measure of energy, also called work, and it doesn't matter what type of energy it is. Work is normally used to describe mechanical energy but it is still measured in Joules.

What is the difference between work energy and power?
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.
Is energy a performance of work?
Yes, simply. Work done (mechanically, electrically) is numerically equal in joules to the energy expended as the work is being done. Think of it as two halves of the same coin.

The work done by the stretching body is equal to the difference in potential energy stored in the spring before and after it is stretched. This work is done against the restoring force of the spring.
Why it is not correct to say that potential difference is the work done in moving unit charge between the point concerned?
Voltage is defined as potential difference (units of volts). Work is equivalent to power (over time), and its' unit is joules. Power is equivalent to the potential difference times the current flow. Without current flow, there is no power, so it is incorrect to define potential difference as work. What I think you're implying is potential energy and potential difference are the same: Potential energy of a rock can be increased by raising the rock into the air. The increase of potential energy of the rock is equivalent to the real work done to raise it higher into the air. This is a true statement. Potential energy (joules) and potential difference (volts) are not equivalent, though, since potential differenence is not defined as work.

What is difference between work and energy?
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.
What is the difference between power and work in the context of physics?
In physics, power is the rate at which work is done, while work is the transfer of energy that results in a change in an object's position or motion. Power measures how quickly work is done, while work measures the amount of energy transferred.
