Newtonian Gravity: Crash Course Physics

The video explores Newton's contributions to physics, focusing on his law of universal gravitation. It begins with the famous story of Newton's apple, leading to his realization of gravity as a force between objects. Newton's formulation of the gravitational law is detailed, including the role of mass and distance. The video also discusses Kepler's laws of planetary motion and how Newton's work validated them. Finally, it highlights modern applications of these principles, such as NASA's use of gravitational calculations for Mars missions.
