The way in which a body moves when under the influence of gravity, and possibly other forces, requires the study if vector calculus. The net forces cause acceleration in the motion. The velocity of the body is the integral of the acceleration and displacement is the integral of velocity.
Gravity is a force, which means that it has a corresponding acceleration (rate of rate of change). Because calculus is the study of rates of change, accelerations are studied in calculus.

Calculus.
Sir Isaac Newton. He and Leibniz both invented the calculus independently.
Basic calculus usually starts with limits. After that you continue with derivatives, and eventually you get to do integration.
Newton Invented it for his theory of gravity.
If you mean Sir Issac Newton, calculus and gravity.
Newton developed his Law of Gravity and calculus when he was away from the university.
The derivation of the equation Emc2 is related to calculus through the concept of energy and mass conversion. Calculus helps in understanding the rate of change and how energy and mass are interconnected, leading to the development of this famous equation by Albert Einstein.
Pretty much everything can be applied to calculus, and calculus to everything. If you have ever read the novel "Halo" you can see (in the first book) that Master Chief, had forgotten how much gravity was on the space-craft, and used calculus to determine the acceleration of gravity by timing the drop of a bolt and figuring out everything else. Calculus is especially important for any kind of profession that involves projectiles.
Gottfried Liebniz and Isaac Newton are credited with co-developing the Calculus, based on work from Archimedes, Cavalieri, and others. But only Newton also studied gravity, and attempted to come up with a theory about how and why it worked.
Isaac Newton. He invented Differential Calculus before the age of 26, and some say he continued to discover and explore it at the same rate that we learn about it today.
