To get it there you have to apply a force to overcome gravity for a certain distance the height of the table.
Force of rubber band.
3 16 inch orthodontic elastic rubber bands 300 pack natural heavy force 6 5 oz.
Rubber polymers chain together to form an entropic spring and is a standard example of an entropic force.
After you get the rubber band stretched just a little bit it is very spring like.
Even if the wheels do spin there might not be enough friction with the ground causing them to spin in.
In rubber the elastic force is due to the thermal interactions of the molecules within the material.
Say i have a rubber band wrapped around 2 pegs at a certain distance and at that distance i know the pounds of force per inch it is pulling at.
For bows dreadlocks dreads doll hair braids horse mane tail tooth gap top knots free elastic placer by cayenas 4 2 out of 5 stars 69.
For example if the pegs are placed such that the band is stretched to 52 inches the force the bands apply to the pegs are 57 6 lbs per inch.
The gravitation potential energy is equal to the force times the distance the.
This is equal to one half the mass of the rubber band multiplied by its velocity in meters.
In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m.
Understanding the physics of elasticity requires a knowledge of advanced mathematics chemistry and statistical physics particularly the concept of entropy.
How much does the rubber band stretch when you hang the object from the end of the board.
There are several molecular mechanisms that work together to produce the elastic force.
To investigate how a force parallel to an inclined plane changes find a rubber band some objects to hang from the end of the rubber band and a board you can position at different angles.
