1 23 know the the initial linear region of a force extension graph is associated with hooke s law.
Force extension rubber band.
In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m.
After you get the rubber band stretched just a little bit it is very spring like.
If you repeatedly stretch and release a rubber band you can feel the effect of heating caused by hysteresis.
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.
Piece of elastic stretches when a load force is applied and the amount by which the stretch is reduced when the load is removed.
