11/10/2009 · A 325 N force acts on an object with a mass of 42.5 kg at an angle of 27° , pulling the object along a flat surface. The coefficient of friction is 0.21 and the object's displacement is 320m. Calculate the net work done on the object. Ok, so I know FN in this case is equal to Fg, and the work done... Add those forces up to get a single “resultant” or “net” force Use F = ma to calculate the object’s acceleration due to those forces Use the object’s acceleration to calculate the object’s velocity

To find the work done by each force, we should recall the formula definition of work. Work equals Fd cosine theta, where theta is the angle between the force doing the work and the direction the trashcan is moving. There are four forces involved here-- tension, the normal force, the gravitational force, and the force of kinetic friction. In finding the work done for all of these forces, the... Preliminary Information: To explore the definition of work and learn how to find the work done by a force on an object. The word "work" has many meanings when used in everyday life. However, in physics work has a very specific definition.

where ?W is the net work and ?F is the magnitude of the net force. You can prove this by calculating the net force for the above scenario, then calculating the work. (You should find that the net force is 3.44 N at an angle of 83.4° below the horizontal.)... The work-energy principle may also be applied, using the fact that in stopping the ball, the kinetic energy would be converted to spring potential energy. It is clear that the two approaches to an average force are not the same, although in this physical system they are proportional.

To calculate the net force, or unbalanced force, of a Newtonian object, find the sum of all forces presently acting upon it. These include gravity, friction and other forces depending on the scenario. You need only a few figures and computations to calculate an object's net force, which is required for acceleration and is expressed in Newtons....
