Detailed explanation-1: -extension is measured in metres (m)
Detailed explanation-2: -extension (e), or increase in length, is measured in metres (m)
Detailed explanation-3: -extension, referring to the increase in length (x), is measured in metres (m)
Detailed explanation-4: -Hooke’s Law states that the force needed to compress or extend a spring is directly proportional to the distance you stretch it. As an equation, Hooke’s Law can be represented as F = kx, where F is the force we apply, k is the spring constant, and x is the extension of the material (typically in meters).
Detailed explanation-5: -F is the force in newtons (N) k is the ‘spring constant’ in newtons per metre (N/m) e is the extension in metres (m) This equation holds as long as the limit of proportionality is not exceeded.
