What did Isaac Newton contribute to science?

A:

Quick Answer

Isaac Newton's greatest contribution to science was his universal law of gravitation, in which he described the laws of gravity after seeing an apple from a tree. According to Encyclopædia Britannica, Newton's law of gravitation suggests that bigger masses attract more strongly and that the distance between masses affects the amount of gravity experienced by each mass, reducing by the square of the distance.

Isaac Newton's universal law of gravitation helped explain why the planets revolved around the sun and led to the development of the laws of motion. The three laws of motion were critical to the evolution of the sciences because they introduced new ways of understanding phenomena in the natural world. The first law stated that an object continues moving forward unless acted upon by an outside force. For instance, if a car traveling at 60 mph suddenly stopped, the car would become a body at rest, but the objects inside the car would continue moving straight forward at 60 mph. The second law of motion explains that the amount of change in the movement of an object depends on the amount of force acting on it. Lastly, the third law of motion, which is Newton's most recited law, states that every action has an equal but opposite reaction.
