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 ...

It is a detailed experiment about extension produced in a spring while loading and unloading. Students are asked to collect data in a clearly labeled table, plot a graph and use the graph to find ...
