Here's a breakdown:
* Elastic Force: This force arises from the tendency of an object to return to its original shape after being deformed.
* Hooke's Law: This law describes the elastic force of a spring. It states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position. Mathematically, it's expressed as:
* F = -kx
* F = Force exerted by the spring
* k = Spring constant (a measure of the spring's stiffness)
* x = Displacement from the equilibrium position (the distance the spring is stretched or compressed)
Important Points:
* Direction: The elastic force always acts in the opposite direction of the displacement. So, if you stretch a spring, the force will try to pull it back to its original length.
* Equilibrium: When the spring is at its normal shape, the displacement (x) is zero, and thus the elastic force is also zero.
