Theoretical Background : An object moving with constant acceleration, its velocity as a function of time is given by : v = v + at Where v is theh initial velocity ( t =0), v is the velocity of the object at time t and a is the constant acceleration. The velocity of the function is : v 2 = v 2 + 2a(x-x ) Where v is the initial velocity (at x ) v is the velocity of the object at x and a is the constant acceleration. Equipment: 1) Computer with ULI interface 2) Air track unit with compressor 3) Wooden block to lift the air track from one side 4) Glider with reflector and top blade 5) Glider weights 6) Photogates attached to stands 7) Motion detector attached to t ripod...
