The equation for spring force is

• F_sp = mgh

• F_sp = 1/2kx²

• F_sp = Fd

• F_sp = -kx

The spring constant of an object tells you?

• What type of spring you are dealing with

• How long the spring will stretch or compress

• It gives you a value on how easy or hard it is to change the objects length.

• A spring constant gives you a number which tells you what material the spring is made of.
