Purpose: To study Newton's Second Law of Motion by examining the acceleration of objects when subjected by different forces, Including friction. Concepts, Given three forces Fi, Fa and Fi, acting on an object of mass m, write down the equations for (1) the net force and (2) the acceleration. Net Force: I F . Acceleration: The unit for the Newton: 1 N = 1 Kgm/s/s. Procedure: For each of the parts (tabs), be sure to click on the available boxes to see the values of the different parometers such as mass, forces, and speed. In Tab 3 and 4, you can also vary the amount of friction to see how its presence affects the acceleration. TAB 1 "Net Force": Figure out the forces of the opposing team (on either end of the rope) and 60 in the blanks. Big blue left + Small red right = Net force of (magnitude) and (direction) Big blue left + Net force of 100 N right . Medium red right . Net force of 150 N left TAB 2 "Motion": Note that there is no friction in this part. 1. Push with 100 N of force for 10 sec on 1 crate, 2 crates, 1 crate + 1 trash bin, the fridge. Record the final velocity for each object. Calculate the acceleration for each object. (NOTE: the last column in the table below is what the expected results). a [F/m) Object(3) m Av 1 oute 2 crates 1 cate + 1 trash bin fridge Analyst, Does the acceleration Increase or decrease with increasing mass? Does this experiment confirm Newton's Second Law equation? That is, is a directly or inversely proportional with massi
