What makes the gravity?

Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an effect on our planet.

What two factors depend on gravity?

The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.

What is gravity not a force?

In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line. In the same way, the straight path of an object is bent when space and time is bent.

Does the gravity on Earth change?

You are right – gravity does change across the surface of the Earth and throughout its atmosphere, due to several effects. First, there is the variation of gravity with latitude that you alluded to: you weigh about 0.5% more at the poles than on the equator. Second, gravity does indeed change with altitude.

Can you turn off gravity?

Many people seem to think NASA has secret training rooms in which gravity can be turned off. Aside from the long-running Anti Gravity column in Scientific American, however, there is no such thing as antigravity. As of yet, no technology exists to neutralize the pull of gravity.

What are 5 facts about gravity?

Six weighty facts about gravity 1. Gravity is by far the weakest force we know. 2. Gravity and weight are not the same thing. 3. Gravity makes waves that move at light speed. 4. Explaining the microscopic behavior of gravity has thrown researchers for a loop. 5. Gravity might be carried by massless particles called gravitons.

What are facts about gravity?

Basic Facts about Gravity. Gravity is the weakest of the four known fundamental forces of nature, yet it is the most dominant force. Even though it is the weakest force, Gravity holds together the entire solar systems and galaxies. The speed of freefall is consistent over the surface of the earth. This means all objects fall at the same speed.

What does gravity stand for?

gravity, gravitation, gravitational attraction, gravitational force(noun) (physics) the force of attraction between all masses in the universe; especially the attraction of the earth’s mass for bodies near its surface. see more ».

What does gravity have to do with?

Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight.
