Homework Statement
Revered Members,
I have attached two images which explain horizontal and vertical oscillations of a loaded spring. In horizontal oscillations the restoring force is taken as F = -kx.
But in vertical oscillations the restoring force is taken as F = kdl.
Homework Equations
The Attempt at a Solution
Restoring force is opposite to the direction of displacement so negative sign is included. But why in vertical oscillations the restoring force is
F = kdl. Why not F = -kdl?
Please help members.
