Investigation of Falling Ball Motion Using Electronic Balance

This study explores the motion phases of a falling ball by analyzing the readings of an electronic balance connected to a PC. The experiment involves a light frame releasing a ball into water in a beaker placed on the balance, with results indicating different motion states. Through detailed phases and moments, the study illustrates the behavior of the falling ball in varying conditions.

2. 5. Falling ball An electronic balance (1) is connected to a PC (5) in order to record the time dependence of the measured weight. A light frame (4) is mounted on a tall beaker (2) filled with water. The frame has a holder (3) allowing controlled release of a small ball such that it falls into the water. The beaker is placed on the balance as depicted in the Figure. Investigate how the readings of the balance reflect the different phases of the motion of the ball.
