Newton's Universal Law of Gravitation Introduction (The Big G Equation)

The video tutorial covers the force of gravity, starting with the basic equation for gravitational force near Earth's surface. It then introduces Newton's law of universal gravitation, explaining the universal gravitational constant and its historical measurement by Henry Cavendish. The tutorial provides qualitative examples of gravitational forces between objects and discusses when to use each gravitational equation, emphasizing the difference between the force of gravity on Earth and the universal law applicable to any two objects.
