What is Gravity? By: Katie Wedell, and Zack Fleege

Gravity Definition Force of attraction between all objects in the universe.

What is gravity?

Sir Isaac Newton’s law of gravitation A point mass m1 attracts another point mass m2 by a force F2 which is proportional to the product of the two masses and inversely proportional to the square of the distance (r) between them. Regardless of masses or distance, the magnitudes of |F1| and |F2| will always be equal.

Sir Isaac Newton’s Life Sir Isaac Newton was born in England in He made many discovers in his very long career of science. His discovers were in areas such as color, light, and planetary orbits. He also discovered gravity. Newton invented a new branch of mathematics called calculus, too! His famous book was the book called “Principia”. But after all of his accomplishments he died in 1727.
