A
The extension of a spring is directly proportional to the force applied, up to the elastic limit.
4

Write Hooke’s law formula.
A
F = k x e
(F = force, k = spring constant, e = extension)
5
Q
What is the elastic limit?
A
The point beyond which the spring will not return to its original shape
6
Q
How do you interpret Hooke’s law data?
A
A straight line means Hooke’s law is obeyed.
