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 = 1⁄2kx 2 , calculate the “maximum” elastic potential energy (PE).
What happen when you stretch the rubber band and release it?
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. ... When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy .
What is the formula for rubber band?
Purpose: To describe the stretching action of rubber bands, and explore the connection between Hooke’s Law and Young’s modulus. 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).
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.
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.
Why does rubber band heat up when stretched?
When molecules, not just rubber molecules, but any molecules, form crystals, they give off heat . This is why the rubber band feels hot when its stretched. When you let go of the rubber band, the polymer molecules break out of those crystals. Whenever molecules break out of crystals, they absorb heat.
How much can a rubber band stretch?
How much does silicone rubber stretch? Some Silicone rubbers can stretch up to 1000%! (That’s about 100x its original length!) Typically the softer the silicone the more it stretches, 20 shore will stretch a lot more than an 80 shore grade.
What happen when you stretch the paperclip?
If we bend the paper clip just a little, it snaps back to its original shape. ... Stretch or bend certain metals (like, for example, the hardened steel of hacksaw blades) and, instead of deforming like paper clips, they just go plink — they break in two all at once.
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.
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.
Does the rubber band have potential energy?
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. ... When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy.
Can rubber be stretched?
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.
How can I permanently stretch rubber?
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.
Does rubber shrink when heated?
The rubber band actually expands when it gets colder ! ... This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.
Does the width of a rubber band affect how easily it can be stretched?
Yosef is curious about the rubber bands, and develops this scientific question: Does the width of a rubber band affect how easily it can be stretched? ... If the width of a rubber band is increased, then it will be more difficult to stretch because more force will be needed to stretch it .
How does the thickness of a rubber band affect its strength?
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.
