What is work and energy physics?
In physics, work is the energy transferred to or from an object via the application of force along a displacement. Work transfers energy from one place to another, or one form to another. The SI unit of work is the joule (J), the same unit as for energy.
What is the definition of 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 mean by work and energy?
Work is referred to as the displacement of an object when a force (push or pull) is applied to it while energy is referred to as the capacity to do the work. It exists in various forms like potential, kinetic, chemical, thermal, nuclear, electrical energy and so on.
What is work class 9th science?
Work: When a force acts on an object and the object shows displacement, the force has done work on the object. Two conditions need to be satisfied for work to be done: (i) A force should act on object. (a) The object must be displaced.

What defines energy?
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and worki.e., energy in the process of transfer from one body to another. For example, any given body has kinetic energy if it is in motion.
What is work energy and Power Class 9?
Work, Energy and Power are fundamental concepts of Physics. Work is the displacement of an object when a force (push or pull) is applied to it. We define the capacity to do the work as energy. Power is the work done per unit of time.
What is energy by BYJU’s?
Energy is the capacity of a physical system to perform work. Energy can be converted in various forms but not created or destroyed. The various forms of energy are solar, wind, hydro, nuclear, thermal, sound, chemical etc. The SI unit of energy is the joule (J) or newton-meter (N * m).
What is work in science 9th class?
