As the rubber is stretched the bonds between adjacent chains are broken. Stretching a rubber band makes it get hot – heat energy is lost. Therefore if you put heat energy into a rubber band it will get shorter – unlike most materials when they are heated.
What happens when you stretch a 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.
Why does a rubber band go farther when stretched?
The more a rubber band stretches, the more energy is stores. When you let go, the rubber band releases the stored energy. As a result, if the rubber band is stretched further, it releases more energy and thus goes further.
Does a rubber band stretch when weight is applied?
If you get hold of a rubber band and pull it you are using a force on it. That force makes the rubber band get longer – it stretches. The greater the pull the longer it gets. In other words a bigger force makes the rubber band stretch more.
Does an unstretched rubber band have energy?
Therefore in the unstretched rubber, energy is much spread out — as is indicated by its high entropy. In contrast, when a rubber band is pulled, its enormous number of lengthy molecules are stretched out and there is less opportunity for free rotation or bending in these conformations.
How much can a rubber band be stretched?
How much does silicone rubber stretch? Some Silicone rubbers can stretch up to 1000%! (That’s about 100x its original length!)Jun 11, 2015.
Does the length of a rubber band affect how far it stretches?
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.
How far can a rubber band travel?
The thicker rubber band flew an average of 98 cm and the thinner rubber band flew an average of 79 cm. The thicker rubber band flew an average of 19 cm farther than the thinner rubber band. So, the thicker the rubber band, the farther it will fly.
How much more weight can the rubber band take without breaking?
The rubber piece will stretch, but not break. The tension throughout the entire band, both thin and thick areas will be 1 kg of force (or to be more scientifically correct — 9.8nt of force). The tension must be constant because every part of the rubber is lifting the same 1 kg weight.
What happens to a spring’s force if you stretch it more?
If a spring is stretched, then a force with magnitude proportional to the increase in length from the equilibrium length is pulling each end towards the other.
Why does a rubber band not have a force constant?
The answer is that they elastically deform by the stretching and bending of bonds between atoms. Stretching bonds increases enthalpy, so when the force is removed, the system wants to give that energy back by returning the bond to its original length.
What kind of energy is stored in the rubber band?
Elastic Potential Energy A stretched rubber band has the potential to do work or change things. This form of energy is called elastic potential energy.
How much energy is stored in an unstretched spring?
The amount of elastic potential energy stored in the spring is equal to the amount of work done or energy applied to stretch the spring. If more amount of force is applied on the spring, then more amount of elastic potential energy is stored in the spring.
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.
How do you calculate the force of a rubber band?
A simple way to understand this formula is Y=stressstrain. The stress is the amount of force applied to the object, per unit area (F/A). The strain is the relative change in the length of the solid (ΔL/L0).
Are thicker rubber bands stronger?
Are thicker rubber bands stronger? 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.
What is the elasticity of a rubber band?
Elasticity of the rubber band is defined as the maximum length the rubber band stretches from its initial length when weight is placed on it. (Dependent Variable) Temperature is defined as the temperature of the water that the rubber band is submerged in (Independent Variable).
When we stretch a rubber band using fingers the net force?
Answer: When a rubber band is stretched, work is done on it , in course of which some amount of energy in the form of elastic potential energy (strain energy) is input into it. This increases the potential energy of the system.
Is stretching a rubber band an example of physical change?
Stretching a rubber band is a physical change because the size of the rubber band changes. The rubber band is still rubber.
When you stretch a rubber band you are applying what kind of stress?
A straight stretched rubber band experiences tension which is a stress that tries to pull matter apart.
Do rubberbands have Hooke’s Law?
Rubber bands provide an interesting contrast to springs. On stretching, they do not obey Hooke’s law very precisely.
How many rubber bands does it take to explode a watermelon?
Watermelon Exploding If you only put 100 rubber bands on it won’t make the rubberband cut in half, but it may make it eventually create a seam in the fruit to release the tension. You will need at least 400 rubber bands to complete this watermelon explosion experiment.
Do rubber bands act like 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.
What happens if you compress a spring too much?
Creep is more often seen when the spring is subjected to high levels of heat for a long period of time, but it can happen anytime extended stress occurs. As a result of creep, the spring deforms as normal but cannot regain its complete normal shape, essentially accelerating the effects of fatigue.
Is spring force constant?
The force exerted by a spring on objects attached to its ends is proportional to the spring’s change in length away from its equilibrium length and is always directed towards its equilibrium position. The proportional constant k is called the spring constant.
What happen when you stretch the spring?
The more you stretch a spring, the longer it gets, the more work you do, and the more energy it stores. If you pull a typical spring twice as hard (with twice the force), it stretches twice as much—but only up to a point, which is known as its elastic limit.
What happens when you stretch a 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.
Why do rubber bands break when stretched?
They don’t have as much entropy as they did before the rubber was stretched. When molecules form crystals they give off heat hence the reason the rubber band gets hot when stretched. When you let go of the rubber band the polymer molecules break out of the crystals.
Does a rubber band stretch when weight is applied?
If you get hold of a rubber band and pull it you are using a force on it. That force makes the rubber band get longer – it stretches. The greater the pull the longer it gets. In other words a bigger force makes the rubber band stretch more.

How much can rubber stretch?
Rubber elasticity refers to a property of crosslinked rubber: it can be stretched by up to a factor of 10 from its original length and, when released, returns very nearly to its original length. This can be repeated many times with no apparent degradation to the rubber.
Do rubberbands have Hooke’s Law?
Rubber bands provide an interesting contrast to springs. On stretching, they do not obey Hooke’s law very precisely.

What is the K value of a rubber band?
Spring constant of the rubber band is k=45.0N/m.
Does a rubber band have elastic spring force?
A rubber band or a spring that is lying on the table does not possess elastic potential energy and is unable to move by itself unless a force is applied to it.
How far can a rubber band fly?
How far can a rubber band fly? The thicker rubber band flew an average of 98 cm and the thinner rubber band flew an average of 79 cm. The thicker rubber band flew an average of 19 cm farther than the thinner rubber band.
How much energy can a rubber band store?
This means that if I stretch the rubber band a distance of about 20 centimeters (that’s around the breaking point) then there would be 1.8 Joules of energy stored in it.
Can rubber shoes be stretched?
Fortunately, you can easily stretch out rubber boots so they fit snugly and comfortably. You can use ice to stretch out the toe, or use heat to loosen up uncomfortable areas. For a full stretch of the foot of your rubber boots, use a good old-fashioned boot stretcher.
Which is more elastic rubber band or spring?
A spring is more elastic to rubber band meaning it has a great resistance to deformation.

Is rubber band flexible?
Rubber is made of flexible long-chain molecules tied together in places by bonds known as crosslinks that connect atoms in adjacent chains. The arrangement looks like strands of spaghetti stuck to each other at random points. The jiggling is driven by heat, the usual driver of molecular motion.
What is elastic spring force affected by?
Factor 1: The extent to which (how much) the elastic object is stretched or compressed. An elastic object that is more stretched or compressed would have more elastic spring force acting on it. An elastic object that is neither stretched or compressed would NOT have elastic spring force acting on it.
Does a stiffer spring have more elastic spring force?
A less stiff object can be stretched or compressed more easily. Comparing two elastic objects, more elastic spring force would act on the stiffer elastic object when they are stretched or compressed by the same length.
Is elastic spring force a non contact force?
In the case of elastic spring force, the force occurs only when the spring is being compressed, so it is also a contact force. There is no contact between cob and paper yet the force occurs hence it is a non-contact force.
