Objective: The objective of this lab to investigate Newton’s First Law and it’s validity in the world. Description: By using a force table, we are able to see the distribution of forces in different directions and magnitudes through the use of pulleys that were assigned different weights. Three to four pulleys are all attached to strings that are tied together in the center of the circular force table. When the pulleys and respective weights are in equilibrium, the center knot of the strings will be in the exact middle of the force table. Theory: Newton’s First Law states that an object at rest will stay at rest unless acted upon by an unbalanced force. It also states that an object in motion will stay in motion unless acted upon by an outside force. If all the forces on an object add up to zero, then the velocity will end up constant. This is the concept of inertia which leads to Newton’s 2 nd law. If f=ma when there is no acceleration (a=0), then the velocity or the integral of acceleration is a constant.
