IB Physics Circular Motion and Gravitation: Gravitational Force

This video tutorial covers the concept of gravitational force, focusing on Newton's law of gravitation. It explains the attractive force between masses, the application of Newton's third law, and the calculation of gravitational force using the law of gravitation. The tutorial also discusses point masses, provides sample calculation questions, and summarizes key points and common questions related to gravitational force.
