Quick Answer: What Does It Mean If An Object Is Elastic?

Which material is more elastic?

SteelSteel is more elastic than rubber.

This is explained with the help of Young’s modulus..

Is metal elastic or inelastic?

Metal wires: inelastic, ductile. Silly putty: inelastic, ductile (some may say brittle; see step 9) Metal springs: elastic (some may say ductile if the spring is stretched too far; see step 10)

What is the difference between elastic and inelastic collision?

An elastic collision can be defined as a state where there is no net loss in kinetic energy in the system as the result of the collision. An inelastic collision can be defined as a type of collision where this is a loss of kinetic energy.

What is the reason for elastic deformation?

Elastic deformation can be caused by applying shear forces or tension / compression stress. In contrast, plastic deformation occurs when these stresses are sufficient to permanently deform the metal. In plastic deformation, breaking of bonds is caused by the dislocation of atoms.

What are some elastic objects?

Examples: Rubber bands and elastic and other stretchy materials display elasticity. Modeling clay, on the other hand, is relatively inelastic and retains a new shape even after the force that caused it to change is no longer being exerted.

What are the elastic properties of solids?

basics. Elasticity is the property of solid materials to return to their original shape and size after the forces deforming them have been removed. Recall Hooke’s law — first stated formally by Robert Hooke in The True Theory of Elasticity or Springiness (1676)… As extension, so force.

Which is more elastic steel or glass?

Ductile materials are used for making springs and sheets. … Due to this reason, steel is preferred in making springs in comparison to steel. Glass is more elastic than rubber because for a given applied force per unit area, the strain produced in glass is much smaller than produced in rubber.

Is a football an elastic object?

Colliding objects do not usually stick together and continue to move as one object. Most collisions are not elastic, either. Even nearly elastic collisions, such as those between billiard balls, result in some decrease in kinetic energy. For example, a football deforms when it is kicked.

How can an object be referred to as elastic?

elastic: Capable of stretching; particularly, capable of stretching so as to return to an original shape or size when force is released.

Why is the elastic Behaviour used?

Below the elastic limit, we say that the spring is showing “elastic behaviour”: the extension is proportional to the force, and it’ll go back to it’s original length when we remove the force. … This means that when a force is applied to deform the shape, it stays deformed when the force is removed.

What is transferred when work is done?

Work is the measure of energy transfer when a force (F) moves an object through a distance (d). So when work is done, energy has been transferred from one energy store to another, and so: energy transferred = work done.

What are the 3 modulus of elasticity?

There are three modulus of elasticity namely Young’s modulus (Y), Bulk modulus (K) and modulus of rigidity (η) corresponding to three types of the strain.

What is elasticity and example?

Elastic goods are goods that have a significant change in demand or supply in response to a change in price. … Using demand as an example, if the price of a good were to decrease by X amount, there would be a greater increase in the amount that people would want to buy.

Do objects stick together in an inelastic collision?

People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision. Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved.

What are two types of deformation?

When a rock is subjected to increasing stress it passes through 3 successive stages of deformation. Elastic Deformation — wherein the strain is reversible. Ductile Deformation — wherein the strain is irreversible. Fracture – irreversible strain wherein the material breaks.

What is meant by elastic behavior?

Elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability is said to behave (or respond) elastically.

What is elastic and inelastic deformation?

A change in shape is called deformation : elastic deformation is reversed when the force is removed. inelastic deformation is not fully reversed when the force is removed – there is a permanent change in shape.

What is the most elastic substance?

rubberElasticity is the ability of a material to regain its own original shape after being stretched according to which, rubber is the most elastic substance. But when we define elasticity in physics it is the ratio of stress to strain. It means that the shape which has more resistance to change is more elastic.

What is the difference between limit of proportionality and elastic limit?

The limit of proportionality refers to the point beyond which Hooke’s law is no longer true when stretching a material. The elastic limit of a material is the furthest point it can be stretched or deformed while being able to return to its previous shape.

Is a property of solids to be broken into pieces?

We will describe solids as brittle if they break into pieces, such as ionic or covalent solids. Metals don’t usually break into pieces, but they can stretch into wires (ductility) and be pounded into sheets (malleability). Conductivity is another important type of property.

Are Diamonds elastic?

Abstract. Diamond is the hardest natural material, but its practical strength is low and its elastic deformability extremely limited.
