Elastic force is the restoring force exerted by an elastic material when it is deformed, causing the material to return to its original shape and length. This force is described by Hooke's Law, which states that the force is directly proportional to the displacement within the elastic limit of the material.

Elastic force

A restoring force is a force that acts to bring a system back to its equilibrium position. It is typically proportional to the displacement from equilibrium and is a fundamental concept in understanding oscillatory motion and stability in physical systems.

Deformation refers to the change in shape or size of an object due to applied forces or changes in temperature. It encompasses both elastic deformation, which is reversible, and plastic deformation, which is permanent, and is a critical concept in fields such as materials science, geology, and mechanical engineering.

Hooke's Law states that the force needed to extend or compress a spring by some distance is proportional to that distance, as long as the elastic limit is not exceeded. This principle is fundamental in understanding the behavior of elastic materials and is mathematically expressed as F = kx, where F is the force applied, k is the spring constant, and x is the displacement from the equilibrium position.

Hooke's Law

Force is a vector quantity that causes an object to undergo a change in speed, direction, or shape. It is described by Newton's laws of motion, which outline how forces interact with mass and acceleration.

Displacement is a vector quantity that refers to the change in position of an object, defined as the shortest path between the initial and final points in a specific direction. It is distinct from distance, which measures the total path traveled regardless of direction, making displacement crucial for understanding motion in physics.

displacement

The elastic limit is the maximum stress or force per unit area within a solid material that can arise before the onset of permanent deformation. Beyond this point, the material will not return to its original shape when the stress is removed, leading to plastic deformation.
