Work, or course, requires energy. A unit of energy is required to do a unit of work. We use the same unit for both: the joule.
That energy is not lost - the law of conservation of energy - it is just converted to another form.
So chemical energy in the sugars in my muscles lift 100g 1m. That requires 1 joule of energy. The 100g weight now has 1 joule more of potential energy. If i drop the weight 1 meter, it gains 1 joule of kinetic, or moving energy. When it hits the desk, it bends the substance of the desk, heating it up, creating heat energy. The sound waves also carry away energy, which will also end up as heat as they are absorbed.
So the energy remains, converted from one type of energy to another, as various types of work are done.

How is energy relate to work?
Basically, work refers to an energy transfer.
The ability to do work is a definition of?
Energy is the ability to do work or cause change.
Is work the transfer of energy?
In a sense, work can be seen as the transfer of energy between a system and its surroundings. When work is done on a system, energy is transferred to it, and when work is done by a system, energy is transferred to its surroundings. This transfer of energy through work is a fundamental concept in physics.
How energy differ from work energy?
Energy is the ability to do work, and work is the transfer of energy from one object to another by applying a force over a distance. In other words, energy is a property of a system that allows it to do work, while work is the process of transferring that energy between systems.
Which forms of energy can do work?
The forms of energy that do work is kinetic energy.
How is work and enegry related?
Work and energy are related in the sense that work is the process of transferring energy from one system to another. When work is done on an object, energy is transferred to that object, either increasing its kinetic energy (if the work is done against friction) or potential energy. The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy.
How is energy and work related?
Energy is the ability to do work, and work is the transfer of energy. When work is done on an object, energy is transferred to that object, causing it to move or change. The amount of work done is directly related to the amount of energy transferred.
What is the relationship between work and energy?
The relationship between work and energy is that work is the transfer of energy from one object to another. When work is done on an object, energy is transferred to that object, causing a change in its state or motion. Energy is the ability to do work, and work is the process of transferring energy.
Is work and energy the same thing?
No, work and energy are not the same thing. Work is the transfer of energy that occurs when a force is applied over a distance, while energy is the ability to do work. Work is a way to transfer energy from one object to another.
How is work and energy related in the context of physics?
In physics, work and energy are related concepts. Work is the transfer of energy that occurs when a force is applied to an object and causes it to move a certain distance. Energy is the ability to do work, and work done on an object changes its energy. The relationship between work and energy is described by the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy.
What is the relationship between energy and the capacity to do work?
Energy is the ability to do work. The more energy something has, the more work it can do. Energy is required to perform any kind of work, and the amount of energy available determines the capacity to do work.
What is the capacity of energy to do work?
The capacity of energy to do work is known as its potential energy.
