We learned how spring force work. We use the equation, F = -kx. which F is the apply force, k is spring constant and x is how much spring displace from its original shape. This is part of the lab, where we are required to use the phet website to figure out spring constant and elongation and put those data in a table and graph them out. Afterward, we were required to use the information we had already found out and use to find the unknown mass of the 3 colored objects (red, tan and green).
