Question

Which two scientific theories were developed by Isaac Newton?

Answer 1

The three laws of motion, and the force of gravity...

Answer 2

The correct answers are A. Three laws of motion and E. Force of gravity.

Explanation

Isaac Newton was a seventeenth-century English physicist who stood out for the content of his book Principia in which he established the principles of gravitation and classical mechanics (Newton's laws). The laws of the force of gravity were developed empirically by Newton when he saw an apple fall from a tree which caused him to wonder why the bodies were attracted to the earth. On the other hand, Newton's laws, or laws of motion are: the law of inertia, which states that a body cannot by itself have its initial state at rest or movement; the second is the fundamental law of dynamics that states that the acceleration of a body is proportional to the force applied to it; Finally, the third law is the law of action-reaction, which states that when a body A exerts a force on an object B, it receives a force of equal magnitude from object B. So, the correct answers are A. Three laws of motion and E. Force of gravity.
