WebWe can define power as the rate of doing work or simply the work done in unit time. The SI unit of power is Watt (W). Work is defined as a force causing the movement or displacement of an object. The SI unit of work is joule (J). We can define time as time taken to do work. The SI unit of time is seconds (s). WebIn a previous part of Lesson 1, work was described as taking place when a force acts upon an object to cause a displacement.When a force acts to cause an object to be displaced, three quantities must be known in order to calculate the work. Those three quantities are force, displacement and the angle between the force and the displacement. WebPower in physics is the amount of work done divided by the time it takes, or the rate of work.

WebJul 6, 2014 · would it be correct to calculate work as the change in PE for the weight: W = ΔPE = (m) (g) (h) = (225 lb) (32.17) (2 ft) It would be correct, but the way you did it is incorrect. Remember: 225 lb is not the mass of the object, it's the weight of the object. So ΔGPE would just be 225lb*2ft Last edited: Jul 5, 2014 Jul 5, 2014 #3 Dale Mentor WebEnergy is defined as a system’s ability to do work. Work is defined as the amount of energy transferred due to an object moving some distance because of an external force. Power is the rate at which energy is transferred or transformed with respect to time. Work, energy, and power are scalar quantities. fish oil 300-500 mgWebi.e. Work is the scalar product of the vectors Force and displacement, not necessarily distance. Scalar product is so called because it returns a scalar, which in this case is Work. (It is also called "dot product" because of the "·" symbol between the vectors in the formula.) fish oil 3000 mg
