definition of elasticity

The term 'elasticity' is used to refer to that capacity of physics that allows some elements to change their shape according to whether they are under physical stress (that is, stretching) or whether they are in their resting position. Some materials have the property of being particularly elastic and are therefore used for the manufacture of products in which this property is useful (for example, some fabrics that must adapt to the shape of a person's body).

Property of some elements to be able to change shape if they are under an external force and then recover their initial format

Elasticity is the ability of bodies to present deformations when they are subjected to external forces that can cause the aforementioned deformations to become irreversible, or, failing that, to adopt their original shape once the action of these forces has disappeared.

Elasticity is a property that applies to various elements both natural and artificial (that is, man-made). This property means that the element itself has a shape, a size and a certain type of features in a state of rest that vary when stretched or put under tension. A clear example of elasticity is, as seen in the image, an elastic band that is made of rubber (a certainly elastic material). While at rest it has a specific shape and size, under tension it can enlarge, twist, wrinkle, etc.

Many elements such as paper, glass (in a cold state), cardboard, ceramics are elements that do not have any elasticity and that in the event of tension or shock are destroyed, losing their original shape and cannot be reassembled. naturally.

Elasticity is a property that is also found in many organs, tissues and muscles of organisms, this being related to the ability to grow and become elastic according to different situations. A clear example of an elastic organ is that of the stomach, which can increase several times its original size and then return to its resting state after the feeding process has been carried out. Normally, in the case of organs and muscles, elasticity has to do with proper hydration since the absence of water (as with skin) cracks and atrophies the different tissues.

Benefits that elasticity brings to the human body

There are many benefits that elasticity brings to our body and therefore it is very important that we carry out stretching routines that have the mission of recovering and maintaining it.

For those who train or do sports, this exercise cannot be missed because it will undoubtedly improve performance.

Human beings are born flexible, with a tremendous elastic capacity, we only have to take a look at children and that fabulous elastic disposition that they present in all their movements, however, with the passing of time, if they do not exercise accordingly, unfortunately , it will be lost.

Now, we must bear in mind that before doing the stretching we have to perform a mini pre-warm-up routine, you should never stretch while cold because an injury may occur.

Among the varied and many benefits that stretching provides, we must mention the following: increased power, resistance, improved posture, efficiency in the functioning of joints, tendons and muscles, decreased risk of injury or other serious risks from falls, prevention of contractures, contribution of muscle relaxation, easy physical recovery, among others.

Economic elasticity

On the other hand, in economics we find the use of this word to designate the concept of economic elasticity, closely linked to the issue of prices since it implies the measurement of variation between the quantity of a product that has been sold and the variations that has shown its price, increase or decrease.

One of the most commented premises in market economy says that if the price of a product rises, the demand for it tends to fall while in the opposite case, that is, if the price of something falls, then it will be more demanded.

Ability to adapt to a new situation

On the other hand, the concept of elasticity is often used a lot in common language to refer to the ability of a person to adapt to a new situation or context.
