How did Newton explain gravity?

In Principia, Newton described gravity as an ever-present force, a tug that all objects exert on nearby objects. The more mass an object has, the stronger its tug. Increasing the distance between two objects weakens the attraction. The truth is, Newton could describe gravity, but he didn’t know how it worked.

Is Isaac Newton gravity?

Legend has it that Isaac Newton came up with gravitational theory in 1665, or 1666, after watching an apple fall. “He showed that the force that makes the apple fall and that holds us on the ground is the same as the force that keeps the moon and planets in their orbits,” Martin Rees says.

What was Newton’s inspiration for gravity?

Interesting Facts about Isaac Newton Legend has it that Newton got his inspiration for gravity when he saw an apple fall from a tree on his farm. He wrote his thoughts down in the Principia at the urging of his friend (and famous astronomer) Edmond Halley.

Did bhaskaracharya discovered gravity?

KP Oli stated, a man named Bhaskaracharya discovered the gravity before Newton. He lived in India amid the twelfth century while Newton was from seventeenth century. The essential field of work of Bhaskaracharya’s was on calculus.

What is Einstein theory of gravity?

GETTING A GRIP ON GRAVITY Einstein’s general theory of relativity explains gravity as a distortion of space (or more precisely, spacetime) caused by the presence of matter or energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime.

How does Newton’s 2nd Law relate to gravity?

Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In this case, the constant acceleration due to gravity is written as g, and Newton’s Second Law becomes F = mg.
