The amount of force required to deform a spring is directly proportional to the length that the spring is stretched inversely proportional to the value of the spring constant indirectly proportional to the value of the spring constant inversely proportional to the length the spring is stretched

directly proportional to the length that the spring is stretched.

Explanation: Deforming a spring means stretching it or compressing it, and the equation that describes this force is:

F = K*X

Where K is the spring constant, and X is the difference between the spring at rest and the actual length of the spring, so X is the distance that the spring has been stretched or compressed.

Then, the force needed to deform a spring is directly proportional to the length that the spring is stretched.
