D. Newton’s laws of physics

Newton’s Life and Laws-

7. Start of paragraph 7 of 9Newton’s three laws of motion are the foundation for today’s study of physics. The first law states what may today seem obvious, but at the time was revolutionary. An object at rest will stay at rest unless it is acted upon by an external force. In other words, a ball won’t soar across a soccer field unless someone kicks it, nor will a car drive down the road unless someone presses the gas pedal.

8. Start of paragraph 8 of 9Newton was not just interested in physics, however, and his work to understand light and optics revealed one of his greatest troubles. Isaac Newton could not handle criticism. In 1672, Newton published the book Opticks: Or, A Treatise of the Reflections, Refractions, Inflections and Colours of Light. It was ill-received by fellow-scientist Robert Hooke, who also studied light. Hooke believed light to be formed by waves, while Newton theorized it was formed by particles. Newton flew into a rage. In later years, he suffered a breakdown and withdrew from public life entirely. His work was everything to him, and when it was criticized, he suffered. Newton’s work cost him a great deal.
