Force extension rubber band.
If you repeatedly stretch and release a rubber band you can feel the effect of heating caused by hysteresis.
Under stress it was shown that the energy absorbed or released by a material is represented by the area between the curve and the extension axis of a force extension graph.
To determine the relationship between the force on a rubber band and its stretch both during extension and retraction.
Determine the approximate percentage by volume of oxygen in air using a 6 12 understand why a force is exerted on a current carrying wire in a magnetic field and 3 25 practical.
1 23 know the the initial linear region of a force extension graph is associated with hooke s law.
In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m.
