Introduction to inquiry (classical method).


Purpose of inquiry By performing a classical experiment from the Galilean era and a modern experiment using Tracker, demonstrate that the distance traveled by a falling object, initially at rest and then accelerating uniformly, is proportional to the square of the time taken to travel that distance. We will compare the results of the two experiments.
Experiment method Slowly drop a sphere from a 3.6 m slope to see if Galileo's claim is correct. The angle of the slope and the experimental method are designed directly.
Basic experiment tools 3.6 m wooden board, long paper box, wooden chopsticks, wood glue, round ice cream bar, iron ball, ping pong ball, golf ball, thread, stand, scale, paper, etc.
Additional experiment tools You can provide your own equipment, excluding modern measuring tools and electronic products (consult with your teacher)
Conditions Because it assumes the era of Galileo, modern measuring equipment cannot be used. Electronic watches, wristwatches, precision rulers, etc.
Precautions If a method has been designed to obtain quantitative data, evidence can be submitted using modern methods such as attaching photographs.
