Question
What is the relationship between force and extension according to Hooke's law?
Answer
According to Hooke's law, the force applied to a spring is directly proportional to the extension of the spring, as long as the limit of proportionality is not exceeded.
Explanation
This answer demonstrates an understanding of Hooke's law, which is fundamental in the study of elasticity. It tests the student's ability to recall and explain the basic principle governing the behavior of springs under load.
Common mistake
Common Mistake in Hooke's Law
Students often confuse the spring constant with the force applied, leading to incorrect calculations of extension.
Remember that the spring constant (k) is a measure of stiffness and should be used as a multiplier in the equation F = k x e, where F is the force and e is the extension.
