What is work done?
Work is done whenever a force moves something over a distance. You can calculate the energy transferred, or work done, by multiplying the force by the distance moved in the direction of the force. Energy transferred = work done = force x distance moved in the direction of the force.
What is work done in short answer?
Work done is defined as product of the force and the distance over which the force is applied. Work is done when a force is applied to an object and the object is moved through a distance. For example, when you lift a load you are applying a force over a distance so you are doing work.
What is formula of work done?
Work done = force × displacement. W = F × s. The SI unit of work is Joule (J).
What is work done in 9th physics?
Work done on an object is defined as the magnitude of the force multiplied by the distance moved by the object in the direction of the applied force. 1 Joule = 1 Newton × 1 metre.
What is work in physics class 9?
Work (W) Work is defined as a force acting upon an object to cause a displacement. It is expressed as the product of force and displacement in the direction of force.
What is work done class 9?
Class IX Science Work Done. • Work done on an object is defined as the magnitude of the force multiplied by the distance moved by the object in the direction of the applied force. Work done = force × distance. = F × s.
What is work done class 11?
Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of applied force. The work done W by the agent is the product of the component of force in the direction of displacement and the magnitude of displacement.
What is work in physics class 11?
In Physics, work is defined as the product of force and displacement. If an object is acted upon by a force, work done is nothing but the product of the magnitude of this force and the displacement of the object caused by the force.
What is the work done in unit time?
Power
Power is the work done per unit of time.

What is work done in electricity?
For electrical energy to move electrons and produce a flow of current around a circuit, work must be done, that is the electrons must move by some distance through a wire or conductor. The work done is stored in the flow of electrons as energy. Thus “Work” is the name we give to the process of energy.
