What is gravitational field mass?
Gravitational field mass, also known as gravitational mass, refers to the property of an object that determines the strength of its gravitational attraction to other objects. It is the mass that appears in Newton's law of gravitation, which describes the force of attraction between two objects based on their masses and the distance between them.
Is Earth the only known planet with gravity?
No, not only the earth and all of the other known planets have a gravitational attraction, but any object of any mass carries with it a measurable gravitational attraction to any other object of mass. Which is why it is said that the moon doesnt just revolve around the earth, for instance, but that the earth and moon REVOLVE AROUND EACH OTHER.
What is the gravitational pull on an object?
That is also known as the object's WEIGHT.
The diagram below shows the force exerted on object m1 due to the gravitational attraction between m1 and m2. What is true about the force exerted on m2 due to the gravitational attraction between m1?
The force exerted on m2 due to the gravitational attraction with m1 is equal in magnitude but opposite in direction to the force exerted on m1. This is known as Newton's third law of motion - for every action, there is an equal and opposite reaction.
Why does a black hole have a lot of power?
I assume you mean the power to attract things. It is for the same reason that our Sun or a galaxy (for example) is powerful; and the reason is the amount of mass. The more mass an object has, the greater its gravitational attraction. Known black holes have masses between a few times the mass of our Sun, and - in the case of some supermassive black holes - about 20 billion times the mass of our Sun, so their gravitational attraction is correspondingly strong.
Motion that is under the influence of gravity alone is called?
Free fall is the term in Newtonian physics used to describe the motion of an object under the influence of gravity alone. Such an object moves along a geodesic. One example of an object always in free fall is Earth's moon.
The amount or concentration of matter in an object is known as what?
The amount or concentration of matter in an object is known as mass.
What is the best known force?
The best known force in physics is the gravitational force, which is responsible for the attraction between all objects with mass.
Is gravitational force also known as weight?
Gravitational force is the force of attraction between two objects due to their mass, while weight is the force of gravity on an object's mass. The terms are related but not interchangeable, as weight is the result of gravitational force acting on an object's mass.
How is weight related to gravity?
You need to know gravity's acceleration to find the weight of an object. This explains why you may weigh X amount on Earth and Y amount on Pluto. Calculate using: F = M * A also known as Weight = Mass * gravity (On earth, gravity's acceleration is ~9.81m/s/s)
How do they measure the earths mass?
-- Take an object of known mass, such as a liter of water.-- Measure the force of gravitational attraction between it and the earth, by placing it on a scale and "weighing" it.-- Knowing the distance from the center of the earth (earth's "radius") and the value of the Gravitational constant,and using the formula for the gravitational force between two masses, the earth's mass can now be calculated.
What is curve of space and time?
Space-time curvature arises from energy densities. It is commonly known as gravitational attraction.
