What is elasticity in physics?

What is elasticity in physics?

Elasticity is the property of a material to return to its original shape after deformation when the external forces are removed.

What is Young's modulus?

Young's modulus is a measure of the tensile elasticity of a material, defined as the ratio of tensile stress to tensile strain.

What is tensile stress?

Tensile stress is the force applied per unit area in the direction of the force, often measured in Pascals (Pa).

What is tensile strain?

Tensile strain is the amount of deformation experienced by a body in the direction of the applied force, measured as a ratio of change in length to the original length.

What is shear modulus?

Shear modulus is a measure of the material's ability to withstand shear deformation, defined as the ratio of shear stress to shear strain.

What is bulk modulus?

Bulk modulus measures a material's response to uniform pressure, defined as the ratio of volumetric stress to the change in volume.

What is elastic limit?

Elastic limit is the maximum amount of stress a material can withstand without undergoing permanent deformation.

What is Hooke's Law?

Hooke's Law states that the deformation (strain) of a material is directly proportional to the applied force (stress) within the elastic limit.

What are the types of elasticity?

The types of elasticity include linear elasticity, nonlinear elasticity, and anelasticity, which describes how materials return to their original shape.

How does temperature affect elasticity?

Generally, increasing temperature decreases a material's elasticity, making it more pliable and less able to return to its original shape.

What is the formula for Young's modulus (E)?

E = tensile stress / tensile strain = (F/A) / (ΔL/L₀) where F is force, A is cross-sectional area, ΔL is change in length, and L₀ is original length.
