LAB 109 Mehar Ghei LABORATORY EXPERIMENT REPORT Name: Mehar Ghei Group Members: Nicole Tran, Yvunne Chen, Nakib Junayed Experiment Date: Tuesday, September 14, 2010 Course Name: PHYS 111A Section: H01 Instructor: Beidi He LABORATORY #109 Velocity as a Function of Time and Distance at Constant Acceleration 1. OBJECTIVE To measure the constant acceleration of an object by various methods, using two different types of apparatus. 2. THEORETICAL BACKGROUND Velocity as a function of time, when an object is moving with constant acceleration, is given by, = + v vo at Where vo is the initial velocity of the object at time t and a is constant acceleration. Furthermore, velocity as a function of displacement is given by, = + ( - ) v2 v ̥2 2a x xo Where vo is the initial velocity of the object at xo and a is constant acceleration. Acceleration with respect to gravity and the angle of inclination is given by, = a gsinθ Where g is 9.8 m/s 2 and θ is the angle of inclination. 3. EQUIPMENT The equipment used for both parts of this lab: Glider with mass Page 1 of 4
