Physics of Falling Objects

In this video, Mrs. Bolden, the 'Goddess of Science Physics,' explains how to solve physics problems involving falling objects. She uses the example of a howler monkey dropping a mango pit to the ground. The video covers calculating the velocity of the pit when it hits the ground and determining the height from which it was dropped. Key formulas involving acceleration due to gravity are used, and the calculations are demonstrated step-by-step. The video concludes with a summary of the results and a closing message.
