In this case both electromagnetism and gravity coul.
Force of a stretched rubber band.
The work done in stretching the unstretched rubber band by l is.
Stretching a rubber band is like moving a brick from the floor to the table top.
But the standard theory of rubbery materials can t predict this force.
Both springs and rubber bands have a special property.
Everybody knows that when you apply a force to a spring or a rubber band it stretches.
I m not sure this question has an obvious answer because parsing your question isn t straightforward.
I m not sure if you re asking.
Which force is applied to a rubber band to make it stretch.
You can easily measure the force produced by a drastically stretched rubber band.
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.
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.
To get it there you have to apply a force to overcome gravity for a certain distance the height of the table.
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.
This can be repeated many times with no apparent degradation to the rubber.
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.
Shoot at least five rubber bands for each stretch length.
Rubber elasticity refers to a property of crosslinked rubber.
Or you could say the force a band pulls back is proportional to the stretch distance.
Shoot more rubber bands in the same way except stretch them back to 15 cm 20 cm 25 cm or 30 cm.
After each launch have your helper.
