Work is application of force, f f, to move an object over a distance, d, in the direction that the force is applied. Work, W , is described by the equation W = f d .

The work done, E w by a force, F moving through a distance, d is given by: \ ( {E_w} = Fd\) Units are joules, newtons and metres. If the force is overcoming frictional forces, all or some of...
In physics, work is defined as the result of a force causing a displacement. Work can be calculated by the equation “Work = Force x Distance”. Here, ‘force’ represents the force applied, ‘distance’ signifies how far an object is moved, and ‘work’ refers to the work done on the object.
In physics, “work” is a measure of the energy transferred to or from an object using a force acting on the object as it moves through a distance. It’s important to understand that work is only done when a force causes displacement or movement in the direction of the force applied.
The amount of work done upon an object depends upon the amount of force (F) causing the work, the displacement (d) experienced by the object during the work, and the angle (theta) between the force and the displacement vectors.
Lesson 1: Work and energy. What are energy and work? What is kinetic energy? What is gravitational potential energy? What is conservation of energy? Work and the work-energy principle.
When a force acts upon an object while it is moving, work is said to have been done upon the object by that force. Work can be positive work if the force is in the direction of the motion and negative work if it is directed against the motion of the object.
