How does the distance affect the force of gravity?
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
How does the force of gravity affect objects in the universe?
Gravity in our universe
Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.
Is gravity one of Newton’s laws?
The Universal Law of Gravitation (Newton’s law of gravity): 1. Every mass attracts every other mass. … Attraction is directly proportional to the product of their masses.
How is gravity related to mass and distance?
The amount of gravity that something possesses is proportional to its mass and distance between it and another object. … His law of universal gravitation says that the force (F) of gravitational attraction between two objects with Mass1 and Mass2 at distance D is: F = G(mass1*mass2)/D squared.
Does weight affect gravity?
Mass does not change with gravity. Weight– the amount of gravity acting on (pulling down on) an object (or mass). Gravity– a natural force that pulls objects downward. Earth’s gravity pulls us and all objects downwards towards its center.
Where is gravity the strongest?
What is the force of gravity on each planet?

What power does gravity have?
The energy that powers gravity is the virtual particle foam of space occurring within the nucleus of atoms. … Gravity is negative energy. The reason is that if you add positive energy to two objects attracted by gravity then the magnitude of the gravitational force reduces, as they move further apart.
How did Einstein explain 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.
What has the greatest gravity?
Is gravity a theory or law?
This is a law because it describes the force but makes not attempt to explain how the force works. A theory is an explanation of a natural phenomenon. Einstein’s General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.
How does mass affect the force of gravity?
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
What are the effects of gravity on objects?
Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth’s gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.
