Hooke's law states that F=kx where F is the spring force. Based on my knowledge, force applied to a spring will change in respect to the elongation of the spring so the force applied is not constant. Then what does F stand for since force on spring is varying? The average force needed to pull the spring over the distance or the maximum force a person has to apply? Or does the understanding have a factual error. Thanks so much!

Why does Hooke's law have a negative sign? the spring force is a friction force the spring force always pushes the mass away from equilibrium it's an arbitrary choice the spring force always pushes back against the direction of displacement
When you hang a 100 g mass from a spring, the spring stretches 2 cm. If you remove the 100 g mass and hang another object of unknown mass, the spring stretches 6 cm. What is the mass of the object? (Assume the spring obeys Hooke’s law and doesn’t stretches beyond its elastic limit). What is the value of the force constant k of the spring in the above problem? HINT: Remember that the force of gravity on a mass (the weight) is given by F = m g, where g = 10 m/s2. Also remember that 1 N = 1 kg m/s2.
If a spring constant of 174 N/m is stretched to a distance of 0.93m, what is the amount of force being placed on the spring at this distance to the nearest whole number? Give only the positive value for your answer(ignore the negative sign)

According to Hooke’s Law, the force (lb), F, required to hold a spring in place when its displacement from the natural length of the spring is x (ft), is given by the formula F = kx where k is called the spring constant. The value of k varies from spring to spring. Suppose that it requires 120 lb of force to hold a given spring 1.5 ft beyond its natural length What, including unit, is the constant value of dF/dx?

Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hooke's law. In laboratory tests on a particular tendon, it was found that, when a 0.255 kg object was hung from it, the tendon stretched 1.25 cm Part A Find the force constant of this tendon in N/m Express your answer in newtons per meter. Part B Because of its thickness, the maximum tension this tendon can support without rupturing is 145 N. By how much can the tendon stretch without rupturing, and how much energy is stored in it at that point? Express your answer in centimeters. Part C Express your answer in joules.
