How do you calculate the energy of a rubber band?
Elastic potential energy (measured in the unit joules) is equal to ½ multiplied by the stretch length (“x”) squared, multiplied by the spring constant “k.” The spring constant is different for every rubber band, but can be figured out (see “Welcome to the Guide to Shooting Rubber Bands” below).
How much energy is in a rubber band?
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.
What happen to the size of a rubber band when you stretch and release it?
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.
How can you change the size of a rubber band?
Although rubber bands seem to never lose their shape or elasticity, you can shrink them by applying heat.
What change takes place on stretching a rubber band?
Answer. Stretching of a rubber band is a physical change. A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. The size or shape of matter may be changed, but no chemical reaction occurs.
Why a rubber band can be stretched?
The reason rubber bands stretch is because when you pull on the rubber band, the polymers (which are normally coiled up more or less at random) get stretched lengthwise and the rubber band is lengthened. This will cause the polymers to stretch and the rubber band to lengthen.
Is stretching a rubber band a physical or chemical change?
Stretching a rubber band is a physical change because the size of the rubber band changes. The color of the rubber band sometimes can change as well when it is stretched. However, the material that the rubber band is made of does not change. The rubber band is still rubber.
Is stretching a rubber band reversible?
The stretching and relaxing of a rubber band is an example of a reversible process.
What happens when a rubber band breaks?
When the rubber band is stretched to the point of breaking, chemical bonds are broken. Given that bond breaking requires energy, it stands to reason that your conjecture has some merit; namely, bond formation is energetically feasible and given enough time should occur, resulting in a reformed band.
Can I take a break from rubber bands?
Elastics can break, and you might feel one snap in your mouth. We recommend carrying spares with you so you can replace the broken elastic with a new one.
What is the effect of force on the rubber band?
Answer. Explanation: Following the relation known as Hooke ‘s law, a 10% percent increase in stretching force will make a typical rubber band 10% longer. But when rubber materials are stretched to twice their original size or more, that simple linear law fails.
Does the width of a rubber band affect the distance?
Yes, the thickness does affect the distance because rubber bands that are thick are harder to stretch then a thin rubber band. Rubber bands that are thicker are harder to stretch, which in my prediction might have a shorter distance.
