#### Transcript of Sir Isaac Newton's Role in the Enlightenment

"The Apple Story"

The story goes that Newton saw an apple fall to the ground and it made him wonder why the fruit always fell straight to the ground; why did it not veer off to the left or right?

Introduction

Isaac Newton had a huge impact on the Enlightenment. Not only did he create calculus, he also described universal gravitation and the three laws of motion.

Universal Law of Gravitation

Newton's equation first appeared in the Philosophiae Naturalis Principia Mathematica.

His theory on universal gravitation also helped to prove heliocentrism, the model of Earth and other planets orbiting the sun. This argued against many religious and traditional beliefs. Newton ideas about the universe became the center of the Enlightenment period.

Calculus

The discovery of calculus is often attributed to two men, Isaac Newton and Gottfried Leibniz, who independently developed its foundations but also had very different views of those foundations.

While Newton considered variables changing with time, Leibniz thought of the variables x and y as ranging over sequences of close values.

**Sir Isaac Newton's Role in the Enlightenment**

It' important to note that Leibniz took a lot of thought into what symbols to use, while Newton did his creation of symbols just based off whatever he wanted to use that day.

Newton's first law

An object in rest will stay at rest unless acted apon by an unbalanced force. An object in motion continues in motion with the same speed in the same direction unless acted apon by an un balanced force.

Newton's Second Law

The rate of change in momentum is is proportional to the imposed force and goes in the direction of that force.

Newton's 3rd Law

For every action there is an equal and opposite re-action

What does this mean?

There is a natural tendency for objects to keep doing what they are doing.

What does this mean?

Heavier objects use more force than lighter objects to go a distance.

What does this mean?

Whenever an object pushes another object it gets pushed back in the opposite direction with equal force
