Newton’s Second Law

3/6/2014

Purpose

The purpose of this experiment is to determine the acceleration of gravity using Newton’s second law.

Equipment

  * Air track, used to place other equipment on to test.
  * Cart, used as the bigger mass in the experiment.
  * String, attached to the bigger and smaller masses.
  * Paper clip, used as a hanger for the smaller mass.
  * Weight set, used to alter the smaller mass.
  * Wood block, used to alter the angle of incline/decline of the track.
  * Meter stick, used to measure thickness of block and distance between supports on the track.
  * Smart pulley, used at the end of the track as a pulley system between the bigger and smaller masses.
Principles

The principles used in the experiment would be Newton’s Second Law, which says that the behavior of objects under a net force is Fnet=ma, and net force is the sum of all forces acting on an object, Fnet=F. The experiment also uses principles of Tension “T” and the force of gravity “Fg”, which is equal to 9.8 m/s².

Procedure
Part A
  * Take the mass of the cart: 253.0 g
  * Add a 10g weight to the 1.0 g paper clip, making smaller mass 11.0g
  * Record the slope of the line of run #1 after releasing the cart to the end of the track.         (y = 0.355x + 0.119)
  * Repeat with another 10g weight, making smaller mass 21.0g
  * Record the slope of the line after run #2 (y = 0.672x + 0.155)
  * Repeat with another 10g weight, making smaller mass 31.0g
  * Record the slope of the line after run #3 (y = 0.966x + 0.268)
  * Repeat with another 10g weight, making smaller mass 41.0g
  * Record the slope of the line after run #4 (y = 1.27x + 0.135)
  * Repeat with another 10g weight, making smaller mass 51.0g
  * Record the slope of the line after run #5 (y = 1.46x + 0.294)
  * Calculate the acceleration for each run using a = mg/(M+m)
  * Run #1 = (11.0g)(9.8)/(253.0g + 11.0g) = .4083
  * Run #2 = (21.0g)(9.8)/(253.0g +...
