Say a spring is on a horizontal table, and the particle is initially at the midpoint of the spring in equilibrium, and then the particle is displaced to one side.
I have attached a diagram, let this side be more to A.
Then I am confused as to which direction the tension in both sides of the spring will act and why.
My thoughts would be along the lines of:
- displaced more towards A, this side of the spring is compressed, the tension will therefore act in the direction AB acting to re-extend the spring (restoring)
- and vice versa with spring B, which is extended and therefore will act to compress
- of course these thoughts are wrong as the tensions would both then be in the same direction.
Thanks alot.
Also upon derviation I am using the time when the particle is intially displaced and so would conclude that the acceleration direction is in the direction BA
