Simple Harmonic Motion Name: Lab Partner: Date Lab day & time: Question: What are oscillations Apparatus One spring that can be mounted vertically Weights Sonic Ranger Calculator Instructions: 1. Attach the spring to the vertical support and measure its spring constant k The spring constant is the force that causes an expansion of the spring divided by amount by which the spring expands. For example, in the figure below AF d. F A F 2. What force would the spring exert if it was extended by 3cm from the equilibrium position?

Explanation / Answer

If df force is applied to stretch spring by d distance then

k =dF/d

Force exerted by spring = restoring force = kx

k =spring constant

for 3 cm extension

Spring force =3x
