[Answer] Which is occurring when work is being done?

In physics work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form it is often represented as the product of force and displacement. A force is said to do positive work if (when applied) it has a component in the direction of the displacement of the point of application. A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force. For example when a ball is held above the ground and then dropped the work done by the gravitational force on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). When the force F is constant and the angle between the force and the displacement s is θ then the work done is given by: ${\displaystyle W=Fs\cos {\theta }}$ Work is a scalar quantity so it has only magnitude and no direction. Work transfers energy from one place to another o…
