How do you find the force of a rubber band?
The stretching action of rubber bands follows Hooke’s Law, F=k x, for small applied forces. The limit of force for which the rubber band follows Hooke’s law depends on the physical properties of the band, such as cross-sectional area.
How much force does a rubber band have?
The rubber band has a mass of 1.09 grams. This puts the specific energy at 1651 J/kg for stretching and 6605 J/kg for twisting. Is that useful? If you are building a rubber band powered car, yes—that will be very useful.
What force is it when you pull a elastic band?
Elasticity and Elastic Force As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force.
What happens to the rubber band?
A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape. That is why a rubber band changes its shape even though it is a solid. Also, if excessive force is applied then the rubber band would break.
What is the K value of rubber band?
45.0N/m
Spring constant of the rubber band is k=45.0N/m.
How does a rubber band have potential energy?
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy.
Is a rubber band a good approximation of a spring?
After you get the rubber band stretched just a little bit, it is very spring-like. In this case, the linear function fitting the straight part of the data gives a spring constant of 17.38 N/m. So, for some cases the rubber band does indeed act like a spring.
How do you find the elastic potential energy of a rubber band?
General Physics. The energy stored in the rubber band is determined by the bands k value (k is called the spring constant), and how far the rubber band is stretched. For each rubber band type, using the formula PE = ½kx2, calculate the “maximum” elastic potential energy (PE).
Do rubber bands melt in boiling water?
Here’s the rub: the problem with rubber bands is that they are not designed to withstand the temperature of boiling water. “Since the boiling point of water is 212 F, there could possibly be some deterioration of the rubber.”
