Force Of A Stretched Rubber Band

In this case both electromagnetism and gravity coul.

Force of a stretched rubber band. After each launch have your helper. Which force is applied to a rubber band to make it stretch. Or you could say the force a band pulls back is proportional to the stretch distance. This can be repeated many times with no apparent degradation to the rubber.

Both springs and rubber bands have a special property. When a rubber band is stretched by a distance x oscillation waves when a rubber band is stretched by a distance x it exerts a restoring force of magnitude f ax bx 2 where a and b are constants. Everybody knows that when you apply a force to a spring or a rubber band it stretches. Shoot at least five rubber bands for each stretch length.

Shoot more rubber bands in the same way except stretch them back to 15 cm 20 cm 25 cm or 30 cm. Attach one end of a rubber band to something that can t move as before and the other end to the force probe hook. It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length. I m not sure if you re asking.

In the 16 february physical review letters researchers make theory agree with experiment by taking into account a previously neglected aspect of the way rubber molecules move. It takes more force to stretch them the farther you pull. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. You can easily measure the force produced by a drastically stretched rubber band.

Pull horizontally on the rubber band with the force probe until the band is stretched to the same standard length used in activity 1 1 and begin graphing while holding the rubber band steady for the whole graph. The work done in stretching the unstretched rubber band by l is. A physicist would ask how is the force that you apply related to the amount of stretch every physics experiment has a purpose often phrased as a question that the experiment hopes to answer. But the standard theory of rubbery materials can t predict this force.

Stretching a rubber band is like moving a brick from the floor to the table top.
