F a a m a 1 2 a m F a = Introduction Objective: This experiment contained 2 parts. The objective of Part A was to make up our own experimental procedure to test the assertion of Newton’s second law that the acceleration of an object is proportional to the force applied on it. The objective of part B was to make up our own experimental procedure to test the assertion of Newton’s second law that the acceleration an object is inverse proportional to the mass of it. Theory: Part A: Part B: The equation that is described by Newton’s second law is To test if the acceleration (a) is inverse proportional to the mass (m) we need to keep the force (F) constant. To do this we use a spring and a constant displacement of that spring so that we have a constant force applied to the glider and small weights to change the mass of the glider. We then need to graph the acceleration versus the inverse of the mass. If the graph obtained is a straight line that intersects both axis at zero then we will have proved that the acceleration is inverse proportional to the mass. Methods and Materials List of Equipment Used: A glider A 1.27 m “frictionless” air track. A photogate timer
