1. Abstract
There are various approach on determining Work, Energy and Power. It usually depends on the given variable or values in the problems. In this experiment N102 titles “Work, Energy, and Power. [1] We determined the power of the fan cart by using the definition of work and the energy conservation principle or Law of conservation. We also observed and computed the work for the motion along a curved path by using the formula W=wL(1-cosɵ). In the first procedure in which we observed the work done and the power needed of the fan cart with added weight by measuring the time in its specific distance. We arrived at a conclusion that the farther the distance covered by the fan cart the slower the time elapsed and the higher amount of work and power is consumed, the power. In the second procedure in which we measured the motion of a curved path we measured it’s angle, distance covered and its height by having a varying force applied into It using the spring balance to record the force applied in Newton.[2] We have observed that the bigger the force applied; there is also increase in height, an increase in its distance covered and with that the work done and its potential energy also increases.[3] We now proved that the theory on conservation of work-energy is therefore true.

[1] Work is said to be done when a force causes a displacement in its own direction. Mathematically, work is given by the product of the force and the distance through which the force acts. Work done by an agent exerting a constant force (F) and causing a displacement (s) equals the magnitude of the displacement s, times the component of F along the direction of
