Newton's Law of Universal Gravitation by Professor Mac

Newton's Law of Universal Gravitation is a law of physics which states that objects attract each other due to their mass. In this video Professor Mac explains the law of gravitation and performs an exciting experiment which demonstrates the consequence of the law on free falling objects. He then starts a journey to explore if gravity exists in space. This is part 1 of the video. Please check on my website http://www.learnwithmac.com for the release status of part 2 of the video.
