Objective:
• Analyze the motion of objects in free fall
• Graph the displacement, velocity, and acceleration as a function of time for an object in free fall
• Evaluate the effect of gravity on an object in free fall
Consider a ball dropped from rest on Earth where the acceleration due to gravity is g=-98 m/s2. If the
ball is dropped from some height above the ground and falls freely (neglect air resistance), fill out the
table with the displacement (Ay), velocity (v), and acceleration (a) of the ball at each second (t).
Consider down as the negative direction.
Identify known variables at any given
