Question

A) Prove the mathematical relationship between Elastic PE and extension. Give example

B)Find a relationship between the Elastic PE and the extension. What happens to the PE as the extension doubles?

You should find a single spring system with a k value (force/spring constant) of 100N/m

Click on ‘Energy plot’ and ‘Values’. Enter data into the Displacement box to apply forces. Record the force applied and Energy below

Displacement/Extension (m)	Force Applied (N)	Elastic PE (J)
0.1
0.2
0.3
0.4
0.5
0.6

Plot a graph of Elastic Potential Energy (y axis) v extension (x-axis) on graph paper.

Allow a scale on your x axis up to 0.7m

C) Draw a line of best fit and use it to predict a value for the Elastic PE stored at 0.7m extension, write your value below:

Value from curve of Elastic PE = _______________ when extension is 0.7m

Explain the main difference in the extension produced by this ‘spring system’ compared to the system
