GRAVITY AND NEWTON DID THE APPLE REALLY FALL?

CENTER OF GRAVITY The point in an object where its weight is evenly balanced is called the center of gravity. This imaginary point is what keeps things balanced. Gravity pulls an object down from its center of gravity. Balancing an uneven shape is easy when you find this point.

SO NOW THAT YOU KNOW ALL ABOUT GRAVITY….WHO DISCOVERED IT?

SIR ISAAC NEWTON Isaac Newton was born on Christmas Day, 1642 in Grantham, England. He was not an exceptional student. After school he went home to work his family farm. However, he was a terrible farmer and instead of watching sheep, he spent his time making models and reading. He went on to the University of Cambridge. Read many books on logic, science, and philosophy. Began to learn math at a rapid pace. Became a professor at age 26.

SIR ISAAC NEWTON The Apple Theory Many say that Newton began to research gravity because he was sitting under a tree and an apple fell off and hit him in the head. There are many accounts of this story, and Newton mentions apples in his writings, but we cannot say with certainty that this is a true event.  Newton used ideas and writings to ask questions about gravity.  Believed that the Earth had a large amount of mass, and that the larger the mass, the greater the force was what attracted objects to it. We now call this force gravity.  Was the first to try to experiment and discover gravity as it extends from Earth towards the moon.

NEWTON’S LAW OF GRAVITATION 1. Any object or piece of matter, from a planet to a pinhead, has an attracting or gravitational force.

NEWTON’S LAW OF GRAVITATION 2. The gravitational force between two objects is proportional to the product of their masses – that is, their masses multiplied together.

NEWTON’S LAW OF GRAVITATION 3. The gravitational force varies with the distance between the two objects. Simply, the force of an object fades extremely quickly the farther away you get.
