The discussion centers on the work done by a stretched spring on a mass as it returns to its equilibrium position. When the spring is fully extended and begins to pull the mass back, the work performed by the spring is positive. This is because the force exerted by the spring acts in the direction of the mass's movement towards equilibrium, thereby transferring energy to the mass.
PREREQUISITESStudents studying physics, particularly those focusing on mechanics, as well as educators looking for clear explanations of work done by springs in dynamic systems.
Please explain why you think it is positive.GBA13 said:Homework Statement
Hi,
I am thinking about a stretched spring with a mass on it. When the spring is fully extended and has just started to pull the mass back towards the equilibrium point, is the work positive or negative?

I think as the spring is pulling the mass then work is positive but I'm not sure. Thanks!
