Q1. What is Hookes law?
Ans. 
Hookes law states that the force needed to extend or compress a spring by some distance is proportional to that distance.
• Hookes law is a principle of physics that states the force needed to extend or compress a spring by some distance is directly proportional to that distance.

• The formula for Hookes law is F = kx, where F is the force applied, k is the spring constant, and x is the displacement of the spring from its eq...read more
