COLLEGE PHYSICS LABORATORY EXPERIMENT MOTION UNDER UNIFORM ACCELERATION OBJECTIVE • Determine whether the motion of an object is taking place under uniform acceleration. THEORY When an object is moving under constant acceleration (denoted a), its average velocity v(t) increases linearly with time t: v(t) = v0 + a t, 2 where v0 is the initial velocity. MATERIAL & PROCEDURE • Material: Sheet with raw data points showing the position of an object every 0.05 seconds. • Procedure: Measure distance covered starting from an initial position and calculate cummulative average velocity. DATA ANALYSIS • Graph Average Velocity versus Time using calculated data • Compute mean values and standard deviations for initial velocity and constant acceleration • Compute percent uncertainty for each quantity
