Question

why gravity is discovered by netwon only?
​

Answer 1

Explanation:

The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest

Answer 2

Answer:

$\underline{\underline{ \sf \huge \red{Answer :-}}}$

• Newton's theory helped prove that all objects, as small as an apple and as large as a planet, are subject to gravity. Gravity helped keep the planets rotating around the sun and creates the ebbs and flows of rivers and tides.

• In all of physical measurements of force and motion, gravity is the only discovery with three- dimensional motion, force and time. ... Galileo seems to have been the first scientist to physically measure the upward acceleration of gravity by timing the motions of different sized balls as they rolled down inclined planes.
