Example activity: how to determine the center of mass of a body if the center of mass is outside the body?

Abstract The centre of mass (CM) is a key concept that facilitates the understanding various physics topics and solution problems. This study’s aim to present an activity for students experimentally determine location CM bodies with outside body. Thus, example will be presented allow understand situation where body, find bodies, generate new examples body themselves. For at-rest common experimental technique finding consists drawing two vertical gravity lines through at intersection these lines. In this research, adapted cases
