If an object of certain mass in sitting on spring, does the act of it's compressing the spring absorb some of it's weight.
For example: -
A) I place an object on a scale and the scale reads 100kg.
B) If I place it on a spring (pretend the spring as no mass) and place the assembly on the same scale under the same conditions will it now read less?
I realise the mass of the object is unchanged. I am interested in the downward force acting on the scale.
