Question

Using principle of conservation of energy ontain the velocity of th body at any point when it is attached to a spring which is displaced to a maximum displacement of x m

Answer 1

By the end of this section, you will be able to:

• Describe the energy conservation of the system of a mass and a spring
• Explain the concepts of stable and unstable equilibrium points

To produce a deformation in an object, we must do work. That is, whether you pluck a guitar string or compress a car’s shock absorber, a force must be exerted through a distance. If the only result is deformation, and no work goes into thermal, sound, or kinetic energy, then all the work is initially stored in the deformed object as some form of potential energy.
