Elasticity is the ability of a material to return to its original shape after being stretched or compressed.
Force of elastic band.
There are several molecular mechanisms that work together to produce the elastic force.
In general the greater the force exerted the greater the amount of deformation.
Both springs and rubber bands have a special property.
A rubber band s elasticity is explained by looking at rubber elasticity and thermodynamics.
This force increases the more the material is stretched or compressed.
In physics and materials science elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed.
This is in contrast to plasticity in which.
In rubber the elastic force is due to the thermal interactions of the molecules within the material.
It takes more force to stretch them the farther you pull.
After you get the rubber band stretched just a little bit it is very spring like.
If the material is elastic the object will return to its initial shape and size after removal.
This is why an elastic band gets longer the harder you pull it and why a rubber ball squashes more the harder you.
This means you can effectively get stronger without.
Or you could say the force a band pulls back is proportional to the stretch.
Understanding the physics of elasticity requires a knowledge of advanced mathematics chemistry and statistical physics particularly the concept of entropy.
In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m.
Elastic potential energy measured in the unit joules is equal to multiplied by the stretch length x squared multiplied by the spring constant k the spring constant is different for.
When an elastic material is stretched or compressed it exerts elastic force.
Solid objects will deform when adequate loads are applied to them.
