Does energy lost equal energy gained?
no
What is Kinetic energy is equal to?
stored energy
When is workdone by force is zero?
work done on an object zero by a force would be zero isif the displacement of the object is zero
What best describes the object's energy as it falls trough the air from the stationary position at height x?
The potential energy it had at height x when it was not moving is equal to the kinetic energy it will have as it is falling. Why? Law of the Conservation of Energy. Energy before will equal energy after.
If an object's mechanical energy is equal to its potential energy how much kinetic energy does it have?
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.
Is there is any workdone in fan when it is rotating and consuming electricity?
The work is done when the fan moves air, imparting kinetic energy to the air.
What is the workdone by central force?
zero
How are work energy and power related?
Work and energy are very closely related. Power is the rate of using energy or doing work. Energy is measured in Joules. Power is measured in Joules per second or Watts. Power P is the time derivative of Work W, P= dW/dt. Power = Workdone or Energy / Time

Is applied force pulling or pushing?
it depends upon the systems displacement and your workdone
Why applying force to an object does not always result in work being done?
When a force (no matter how large it may be) is applied to any object without a distance being moved,it cannot be workdone because,workdone = force x distance.

no
What in a closed system energy is equal to potential energy plus kinetic energy?
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
