NET WORK ON AN OBJECT A number of forces can act on an object at the same time. Each force can do work on the object to change the energy of the object. The net work done on the object is the sum of the work done by each force acting on the object. o If Wnet is positive, energy is added to the system. o If Wnet is negative, energy is removed ...
WORK, ENERGY & POWER LESSON 1: Definition of work. Net work. Alternate method for determining the network. Objective: Learners must be able to: Define the work done on an object by a constant force as ∆ cos𝜃, where F is the magnitude of the force, ∆ the magnitude of the displacement and 𝜃 the angle
