Analysis In the concept of Hooke's Law of elasticity, It is said that the extension of a spring is directly proportional to the force applied on it. Where in Table 1A the Force constant is the rate at which the force needed for the spring to extend in every meter , (An average value of 4.25N is needed to apply to extend the spring to 1 meter) Theoretically using Newton's concept where the value of work is equal to Force x Displacement, the value of the area under the graph (where also consider as work done by the spring ) and the value of the product of Force and X (also consider as work) must have the same value. But when using spring computations will going to be different because when there is a spring in the system, the Potential Energy equation will need to participate to get the correct value of the work done by the spring (where PE = ½kX 2 , Where PE is also the equation to get the work done by the spring ) That is why even both formulas are used in getting the work, they are used in different systems. The slope of the F vs X graph represents the average value of the force constant of
