Elastic Force Of A Rubber Band

Figure a shows the elastic band in an arbitrary configuration described by a function bf x s t and the unit vector pmb tau s t which is tangent to the band at the point bf x s t.

Elastic force of a rubber band.

I m not sure this question has an obvious answer because parsing your question isn t straightforward. There are several molecular mechanisms that work together to produce the elastic force. Understanding the physics of elasticity requires a knowledge of advanced mathematics chemistry and statistical physics particularly the concept of entropy. Elastic potential energy is the stored energy of a compressible or stretchable object like a spring or rubber band or molecule.

F force in newtons. The longevity of the elastic wear may vary from two weeks to several months. In this case both electromagnetism and gravity coul. W elastic potential energy in joules.

After each launch have your helper. Deformation is reversed when the force is removed inelastic deformation is not fully reversed when the force is removed there is a permanent change in shape a rubber band undergoes. Shoot more rubber bands in the same way except stretch them back to 15 cm 20 cm 25 cm or 30 cm. I m not sure if you re asking.

Firstly by pulling back the rubber band racer you stretch the rubber band thereby storing energy also known as potential energy. So for some cases the rubber band does indeed act like a spring. This is nice especially since in the past i used a rubber band to make a diy force probe. So for some cases the rubber band.

Shoot at least five rubber bands for each stretch length. In rubber the elastic force is due to the thermal interactions of the molecules within the material. When you let the rubber band racer go the stored energy in the tension of the rubber band is released and is transferred to the rear axle an application of the first law of thermodynamics. Which force is applied to a rubber band to make it stretch.
