Hooke’s Law Physics Definition:
Hooke’s Law is a principle of physics that states that the that the force needed to extend or compress a spring by some distance is proportional to that distance.
We are giving a detailed and clear sheet on all Physics Notes that are very useful to understand the Basic Physics Concepts.
What is Hooke’s Law in Physics? | Definition, Formula – Elasticity
Hooke’s Law Statement:
Hooke’s Law states that within the limit of elasticity, the stress is proportional to the strain.
Stress ∝ Strain
or
Stress = E x Strain
where, E is the modulus of elasticity of the material of the body.
Hooke’s Law Formula:
Mathematically, Hooke’s law is commonly expressed as:
Fs = k.x
Where,
Fs = spring force
k = spring constant
x = spring stretch or compression
Hooke’s Law Examples Real Life
Buildings are amalgamations of structural frames. Under loading, the individual beams and columns that compose frames display the linearly elastic stress-strain curves that exemplify Hooke’s law.
Elasticity:
Elasticity defines a property of an object that has the ability to regain its original shape after being stretched or compressed. Learn about the deforming force applied on an elastic object and how the stress and strain works on an object. What is a Hooke’s law and how it is applicable for the concept of elasticity.
