(1) Newton's Second Law of Motion – A photogate is used to detect the velocity of a free falling object.  A force sensor can be used to measure the weight of the object to balance the equilibrium equation of Newton’s Second Law of Motion.  Objects of different weight are dropped to develop an understanding of drag in free fall. 

(2) Center of Gravity - A tilting apparatus along with a photogate is used to measure the point which an object begins to tip or slide as the angle of the tilting apparatus is increased. 

(3) Angular Momentum – A photogate and a frictionless pulley is used with a pendulum to see how the frequency of the pendulum varies with a change in length of the string of the pendulum.  With the moment of inertia of the pendulum and the frequency of the oscillation, the angular momentum is be calculated.  Conservation of angular momentum is also verified. 

(4) Pressure – A force sensor, aluminum foil, and some variable cross sections are used to determine the effects of pressure on piercing the aluminum foil.  The experiment illustrates how pressure varies with different cross sectional areas with constant applied force.
