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 ...

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 ...

The spring constant, k, is a measure of the stiffness of the spring. It is different for different springs and materials. The larger the spring constant, the stiffer the spring and the more difficult ...
