Final answer:
The force constant (k) is a measure of a spring's resistance to being compressed or stretched. It is determined by measuring the restoring force exerted by the spring when it is stretched or compressed. The force constant (k) is measured in newtons per meter (N/m).
Step-by-step explanation:
The parameter that measures a spring's resistance to being compressed or stretched is called the force constant (k). It is a property of the spring and is related to its stiffness. The force constant (k) is determined by measuring the restoring force exerted by the spring when it is stretched or compressed. It is measured in newtons per meter (N/m).
