Force Of Rubber Band

How much does the rubber band stretch when you hang the object from the end of the board.

Force of rubber band.

Even if the wheels do spin there might not be enough friction with the ground causing them to spin in. Understanding the physics of elasticity requires a knowledge of advanced mathematics chemistry and statistical physics particularly the concept of entropy. 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. The rubber band can slip relative to the wooden axle preventing the wheels from spinning.

Rubber polymers chain together to form an entropic spring and is a standard example of an entropic force. In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m. 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. This is equal to one half the mass of the rubber band multiplied by its velocity in meters.

To get it there you have to apply a force to overcome gravity for a certain distance the height of the table. There are several molecular mechanisms that work together to produce the elastic force. After you get the rubber band stretched just a little bit it is very spring like. When the rubber band is released the potential energy is quickly converted to kinetic motion energy.

3 16 inch orthodontic elastic rubber bands 300 pack natural heavy force 6 5 oz. The gravitation potential energy is equal to the force times the distance the. In rubber the elastic force is due to the thermal interactions of the molecules within the material.
