Force Of A Stretched Rubber Band

This can be repeated many times with no apparent degradation to the rubber.

Force of a stretched rubber band.

I m not sure this question has an obvious answer because parsing your question isn t straightforward. In this case both electromagnetism and gravity coul. I m not sure if you re asking. After each launch have your helper.

Attach one end of a rubber band to something that can t move as before and the other end to the force probe hook. Everybody knows that when you apply a force to a spring or a rubber band it stretches. 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. Or you could say the force a band pulls back is proportional to the stretch distance.

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. To get it there you have to apply a force to overcome gravity for a certain distance the height of the table. Stretching a rubber band is like moving a brick from the floor to the table top. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and.

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. The work done in stretching the unstretched rubber band by l is. 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. It takes more force to stretch them the farther you pull.

Rubber elasticity refers to a property of crosslinked rubber. But the standard theory of rubbery materials can t predict this force. 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. You can easily measure the force produced by a drastically stretched rubber band.

Shoot at least five rubber bands for each stretch length.
