Calculating the Gravitational Force

Mr. Anderson explains gravitational force in this AP Physics video. He discusses why objects in space appear weightless, using Newton's cannonball thought experiment to illustrate how satellites orbit Earth. The video introduces Newton's law of universal gravitation, explaining the equation and the gravitational constant. Mr. Anderson demonstrates how to calculate gravitational force between two masses and provides an example problem involving the moon. The video concludes by reinforcing the concept that gravity is always present, even in orbit.
