When we are at rest or we are nearer to the surface of the Earth, the gravitational force is similar to the weight of the object. Complete answer: … Hence, the nature of the gravitational force will always be attractive and not repulsive. Thus, we can conclude that gravitational force cannot be repulsive.
Is gravitational force attractive and repulsive?
Both in the Newton theory of gravitation and in the General Theory of Relativity the gravitational force is exclusively attractive one. However, the quantization of gravity shows that the gravitational forces can also be repulsive .
Does gravity always attract or repel?
All massive objects attract each other. Gravity never acts to repel two objects. The more complex answer is that it doesn’t matter how you think of it. The formula for gravitational attraction depends on the mass of each object ( m and M ), the distance between them ( r ), and the gravitational constant ( G ).
Why is the gravitational force attractive?
The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. … And objects that are really far apart from each other don’t pull on each other noticeably either.
Is gravitational force conservative or nonconservative?
vs. If the work done by a force depends only on initial and final positions, not on the path between them, the force is called a conservative force. Gravity force is “a” conservative force.
Does gravity attract gravity?
Gravity does not really attract at all, its the curvature of space-time caused by a concentrated form of mass/energy. However, anything containing mass/energy will curve space-time around it so anything else must follow the curvature of space-time including light for example.
Which of these force is always attractive?
The correct answer is option 2 i.e. Gravitational force. All objects in the universe attract each other. This force of attraction between objects is called the gravitational force.
Why is gravitational force only attractive in nature?
Since as per general theory of relativity effect of gravity takes effect due to distortion of SPACE and TIME it can only attract towards the mass creating gravitational force. Originally Answered: Why is gravity only attractive? Basically, gravity is because of bend in fabric of space time .
Is gravitational force conservative?
A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the path taken. … Gravitational force is an example of a conservative force, while frictional force is an example of a non-conservative force.
How do you prove that gravitational force is conservative?
Work, Energy and Power. Show that gravitational force is a conservative force. A force is said to be conservative if work done by the force is independent of the path followed and depends upon the initial and final positions. Suppose a body of mass m be taken from A to B along different paths as shown in the figure.
Which type of force is gravitational force?
Gravity or gravitational force is the force of attraction between any two objects in the universe. The force of attraction depends on the mass of the object and the square of the distance between them. It is by far the weakest known force in nature.
