In this activity of free fall motion, there are two balls with different mass were used. An object that is moving and being acted upon only be the force of gravity is said to be "in a state of free fall." The objectives of this experiment is to verify that the value of acceleration due to gravity is 9.8 m/s2. And to determine the effect of mass of the object to the period and velocity of fall. Here are the procedures on how to make the experiment: Measure and mark a height of 2 meters from the ground for initial position Find Area Start First Ball Second Ball Weigh the ball Drop ball Record time Make 5 trials Compute Acceleration Gravity Compare true value Results
