Understanding Gravity and Forces

The video tutorial introduces the concept of gravity, highlighting Isaac Newton's discovery when an apple fell on his head. It explains Newton's thought process, likening Earth's gravitational pull to a magnetic force. An experiment using magnets is conducted to demonstrate this concept, concluding with observations on Earth's gravitational force.
