## What happens to the potential energy when a spring is compressed?

When a spring is compressed or stretched, potential energy energy of the spring increases in both the cases. This is because work is done by us in compression as well as stretching.

**How does the potential energy of a spring change if its amount of stretch is doubled?**

If the stretch of a spring is doubled, the force it exerts is also doubled. By what factor does the potential energy increase? energy does not change.

**How do you find the potential energy stored in a spring?**

Section Summary

- Hooke’s law describes force exerted by a spring being deformed, F=−kx,
- Elastic potential energy PEel stored in the deformation of a system that can be described by Hooke’s law is given by. PEel=(1/2)kx2.

### What happens to the period of the spring constant is doubled?

A mass m hanging on a string with a spring constant k has simple harmonic motion with a period T. Thus, if the mass is doubled, the period increases by a factor of √2. A mass hanging from a spring is pulled down from its equilibrium position through a distance A and then released at t = 0.

**What is a reasonable number for a spring constant?**

155 N/m.

**What is the formula for the period of a mass on a spring?**

Period of a Mass on a Spring. The period of a mass m on a spring of spring constant k can be calculated as T=2π√mk T = 2 π m k .

#### What happens to the period of a mass spring system when the amount of mass hanging from the spring is decreased?

They all affect the period of oscillation. What happens to the period of a mass-spring system when the amount of mass hanging from the spring is decreased? A. The period decreases.

**What is the effect of quadrupling the spring constant?**

The greater the spring constant, the harder it is to stretch or compress the spring. The Simple Harmonic Motion Gizmo allows you to manipulate the mass on the end of the spring (m), the spring constant (k), and the gravitational acceleration (g).
