Free Fall

Free Fall Pre-Activity Purpose To determine: 1.The uniform acceleration of an object freely falling near the surface of the Earth. 2.The relationship between the mass of an object in free fall and its acceleration. Lab Notes The Picket Fence must fall straight through the photogate. If it hits or turns, redo the trial! Drop the Picket fence close to the photogate The slope of the velocity vs. time graph is the free fall acceleration You must hit stop before reading the slope (free fall acceleration) The correlation coefficient should be r = Free Fall is uniformly accelerated motion!
