Lesson: Elastic Potential Energy and Conservation of EnergyMathematics
In this lesson, we will learn how to solve problems that include elastic strings and springs by using the work–energy principle and the conservation of energy principle.

A particle of mass 3 kg is attached to end of a light elastic spring of natural length 0.5 m and modulus of elasticity 41 N. The spring rests on a smooth horizontal plane with end fixed. The particle is held at rest and then released. Find the initial acceleration of the particle if initially. Take .
Determine the elastic potential energy stored in an elastic spring of natural length 5 m and a modulus of elasticity 13.4 N, which was compressed to a length of 4 m.
A bowl of mass hangs in equilibrium from the ceiling by a light elastic spring of natural length 0.8 m and modulus of elasticity 7 N. Taking , find the distance the bowl moves when a mass of 1 kg is gently placed in it.
