     Isaac Newton discover the laws of motion and gravity. He did experiments to do with gravity. One thing he discovered no matter how heavy something is or light they will always fall at the same speed. He had a positive influence to the world. You also may know him from the myth when an apple fell on he’s head.]]> 2019-01-15 15:57:10 UTC https://padlet.com/mpulis/4l5a7xqgk00u/wish/320829385 https://padlet.com/mpulis/4l5a7xqgk00u/wish/320829569 1.Thomas Edison2.
