Newton's second law takes this a step further by determining how much force is need to change the state of the object. In the first law, Newton presented the theory that an object in motion stays in motion, and an object at rest stays until an outside force affects them. Do the math for the second law of motion.They will stay in motion until they are stopped when reaching the bottom of the slide.

Newton's first law of motion is known the law of inertia, which states that every object will remain at rest or in uniform motion in a straight line unless acted on by an external force. Experience the first law of motion at the playground.X Research source Eventually, Newton would study how the laws of motion related to the motion of the Earth, Sun, and Moon, a concept he would call 'gravity.' X Research source What are some of the practical applications of the laws of motion? During this time he developed the concept of infinite-series calculus, and laid the groundwork for his three laws of motion.

When Cambridge closed for two years due to the Black Plague, Newton continued to study complex math, physics, and optics on his own. In the 17th century, Isaac Newton was a student at Cambridge University.
