Energy is done when a force causes an object to move?
Work is done when force causes an object to move and capacity of doing work is called energy So, energy is required and consumed when force causes an object to move
Why when you push an object across a desk is the work done not equal to the change in gravitational potential energy?
The gravitational potential energy does not change if the desk is horizontal. The work done is in overcoming the friction between the object and the desk.
How are work and potential energy related?
potential energy can be decreased or increased depending upon the work being done on an object
What determines when work is being done on an object?
work is scientifically defined by power. so we can conclude that work can be determined on an object by if it has energy, or inertia. for example say i pushed a box, i would be transferring my energy to the box, and using my power which would mean i am doing work to the box.
What is is the best definition of energy?
Energy is the power , potential and capability to do any kind of work.our body needs energy to stand , to walk, to run and do any kind of work. without energy we can not do anything.because of energy we are able to live in this world. all things are forms of energy in this worldThere are many different forms of energy,Heat,Light,Motion,Electrical,Chemical, Gravitational etcenergies can be converted from one form to another.
If work done on an object is equal to object's change in kinetic energy this the state of?
the Work-Energy Theorem states the work done is equal to the change in kinetic energy.
The ability to do work is a definition of?
Energy is the ability to do work or cause change.
Why when you push an object across a desk the work done is not equal to the change in gravitational potential energy?
In this case, you are not doing work against the force of gravity, but against the force of friction.
Energy is done when a force causes an object to move?

When you perform work on an object you increase the energy of the object.?
Generally yes, but it really depends on the specific situation. -- If the work is done to lift the object, then the object's potential energy is increased. -- If the work is done to accelerate the object, then the object's kinetic energy is increased. -- If the work is done to move the object against friction, then the energy supplied is dissipated, and the object's energy may or may not change, depending on whether or not it is somewhat heated by the dissipation.
How does energy change when work is done?
Energy changes and object is equal to the net work done. This is taught in science.

potential energy can be decreased or increased depending upon the work being done on an object
Can the total energy of an object change without any work being done Explain?
Energy is a conserved quantity. That means that, if no energy enters or leaves an object, the total energy of this object will remain the same. There are several ways for energy to enter or leave; I am not sure whether all of these qualify as "work".
What cause an object to have potential energy?
Potential energy is stored energy capable of doing work. Since energy is general comes from the food we eat, so does potential energy.
Why can work be the thought of as the transfer of energy?
That is because work requires energy. According to the law of conservation of energy, it can't be created or destroyed. When doing work, energy change forms and gets transferred to the object until it is released. For example, when you lift up an object and place it on a higher elevation, you gave transferred energy to it and gave it potential energy. The potential energy is transformed into kinetic energy when the object falls down, and if it hits a surface, the energy will scatter, vibrating the areas around it and producing sound. Also, work= force X distance. The energy does not go away, but rather get changed into some other form (it usually becomes heat and sound).
