Energy is doing work when it is being transferred or transformed to cause a physical change in an object or system. This work can manifest as motion, heat generation, or the lifting of an object against gravity. Work is the transfer of energy that leads to a change in the energy of the system.
What else can I help you with?
How does doing work on an object change its energy?
When work is done on an object, energy is transferred to or from the object, changing its energy. If work is done on an object, its energy increases; if work is done by an object, its energy decreases. The change in energy of an object is equal to the work done on it.
How is energy different from work?
They have the same units- Joules - so can be equated. Work is something actually done, and in doing work energy is expended, but you can also talk of doing work to store energy. For example in running a compressor to fill a cylinder with compressed gas, energy is supplied to the compressor motor, work is done by the compressor, and the result is stored energy in the gas. Fuels such as coal have potential or stored energy, which can be released to do work. So I think the fundamental is energy, but when energy is used, work results. Hope that makes sense!
What is the capacity for doing work It may be transformed from one form to another?
Energy is the capacity for doing work and can be transformed from one form to another, such as from potential to kinetic energy. This principle is known as the law of conservation of energy.
What is the rate of doing work or using moving energy?
The rate of doing work or using moving energy is known as power. It is measured in watts and represents how quickly energy is transferred or work is done. Power is calculated by dividing the work done by the time taken to do the work.
Which type of energy is lost in doing work against friction?
The energy lost in doing work against friction is primarily converted into heat energy. Friction between surfaces causes mechanical energy to be transformed into thermal energy, leading to an increase in temperature in the system.
What do you call some one who uses more energy avoiding work than actually doing the work?
a procrastinator
What work is done without using energy?
If you mean "work" and "energy" in the physical sense, that isn't possible. "Doing work" can be understood as a transfer of energy; doing work requires energy.
What different between power and energy?
Power is the rate of doing work or delivering energy whereas energy is the capacity for doing work.
Do you need energy in doing work?
Yes. Basically, work is the transfer of energy.
What word describes the capacity to do work?
Energy is defined as the capacity to do work. The word "able" applies to a capable of doing work, or doing it correctly.
What is energy about?
Energy is often defined as the potential for doing work
What is the science definition for energy?
Energy is the capability of doing work
How does doing work on an object change its energy?
When work is done on an object, energy is transferred to or from the object, changing its energy. If work is done on an object, its energy increases; if work is done by an object, its energy decreases. The change in energy of an object is equal to the work done on it.
How can energy be use with out doing work?
yes
What type of energy is used by objects doing work?
kinetic energy

What is it a body having an energy capable of doing?
Work. :)
