y = distance stretched vertically
k = spring constant
M = mass of weight on spring
My Physics book says the work to stretch a spring is .5ky2. If I set that equal to the work done by gravity on the weight (9.8xM) and solve for the constant I get k = (9.8M)/(.5y)
My Physics book also says that the force from a spring is ky. If I set that equal to the force of gravity on the weight (9.8M) and solve for the constant I get k = (9.8M)/(y)
Why do I get a different constant??
