1 OBJECTIVE To analyze the motion of an object in Free-Fall by: 1) Analyzing the corresponding equations of motion. 2) Calculating the velocity at different times by using: a) the tangent method b) the equation of motion x = x(t) c) graphical methods ( t x v o t = lim ) 3) Calculating the acceleration of gravity ‘g’ and comparing to the expected value of 9.80 m/s 2 . THEORY Any object moving under the influence of gravity alone, regardless of its initial position, is said to be moving in free-fall. The acceleration of an object in free-fall near the earth’s surface is nearly constant and approximately equal to g = 9.80 m/s 2 . In this lab you will analyze the motion of an object moving in free- fall by using an apparatus called the Behr Free-Fall. The object moving in free-fall is a ‘bob’ that will leave a trail of sparks on a wax paper as it falls through some height H. The sparks will be generated by a spark timer set at a frequency of 60Hz (60 sparks per second). Thus, the trail of sparks on the wax paper
