The spring constant of a spring can be found by carrying out an experiment. The unloaded length of a spring is measured. Slotted masses are added to the spring. Record each stretching force in N and ...

To investigate experimentally the extension of a spring and how it is related to the applied force, and recall that the extension of a spring is directly proportional to the force applied, provided ...

The mass is just sitting there motionless. There is no acceleration and it is in equilibrium. What does this mean? This means that the net force in the y-direction (vertical direction) must be zero. I ...
