Equivalence Principle

Mr. Anderson explains the equivalence principle, highlighting the equivalence of inertial and gravitational mass. He discusses historical contributions by Galileo, Newton, and Einstein, and demonstrates experiments to measure mass using a ruler and balance. The video concludes with a discussion on Einstein's theory of relativity and its connection to the equivalence principle.
