Work done on an object is equal to the energy transferred to the object to make it move or undergo a change in its state. This is based on the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy. In other words, work done represents the transfer of energy from one form to another.

Can workdone by friction be positive?
No, work done by friction is always negative because it opposes the direction of motion. Friction always acts in the opposite direction to the force causing the object to move, resulting in a loss of energy and a decrease in the total mechanical energy of the system.
What do you mean by workdone?
Work done is the measure of energy transfer that occurs when a force causes an object to move a certain distance in the direction of the force. It is calculated as the product of the force applied and the distance moved in the direction of the force. Work done can lead to a change in the energy of an object.
What is equal to the ability to do work?
Energy is equal to the ability to do work. Energy can exist in various forms such as kinetic energy, potential energy, thermal energy, and chemical energy.
What is total minus energy kinetic energy is equal to?
Total minus kinetic energy is equal to potential energy. Potential energy is the energy stored in an object due to its position or state, while kinetic energy is the energy of motion.
Can a objects mechanical energy be equal to its gravitational potential energy?
Yes, an object's mechanical energy can be equal to its gravitational potential energy. Mechanical energy is the sum of an object's kinetic and potential energy, and gravitational potential energy is a type of potential energy determined by an object's position in a gravitational field. When the object is at rest or its kinetic energy is zero, its mechanical energy will equal its gravitational potential energy.
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.
