Newton and His Apple: Simple Newton Physics

"Isaac Newton was a shy, quiet boy growing up on a farm in England 300 years ago. He was not a very good student and nobody paid much attention to him. Nobody that is, except the school bully. One day the bully punched Isaac in the stomach. That hurt, and that got Isaac very mad! He pulled himself up straight and fought back. Isaac pushed the bully onto the ground and rubbed his face in the mud. All the other kids hated the bully and came and cheered for Isaac.So Isaac taught the bully a lesson, but he wasn't satisfied with that. Now that he knew he could fight better than the bully, he wanted to prove that he could do anything better than the bully. So he started paying attention to school and studying hard. He was soon the top of his class, proving he was smarter than the bully too.Isaac Newton kept on studying and when he grew up he became a math professor at Cambridge University. He discovered lots of important things and is one of the most famous scientists who ever lived.But One day Isaac was reading a book under an apple tree on the farm. An apple fell out of the tree - bonk! Ow!Now, for most people that would be the end of the story, but not for Isaac. Not for somebody who just couldn't stop asking why all the time.Why did the apple fall out of the tree? Does everything fall? What makes things fall? Can anything stop things from falling? Are the sun, moon, and stars falling? Why don't they ever hit the ground?So many questions. Newton spent many years answering these questions by thinking and doing experiments. He made up the law of gravity. According to this law everything pulled everything else to itself by a force called gravity. How strong that force is depends on how heavy the things are and how close together..This book telling this excellent biographic story very simple, teaching and amazingly.."
