Force and Newton's Laws: Gravity

The video explains Newton's theory of gravity, starting with the story of an apple falling from a tree. It describes gravity as the force that holds objects in place and attracts them towards the Earth. The concept of universal gravitation is introduced, stating that all objects in the universe are attracted to each other by gravity.
