What are good questions about gravity?

Gravity Questions

• Can gravity form waves?
• Can you go fast enough to get enough mass to become a black hole?
• Do I weigh less on the equator than at the North Pole?
• Does every black hole contain a singularity?
• Does the influence of gravity extend out forever?

How do you determine the direction of gravitational force?

The weight always points toward the center of mass of the earth. On or above another astronomical body, the weight is the gravitational force exerted on the object by that body. The direction of the weight (or gravitational force) points towards the center of mass of that body.

Can gravity be created or destroyed?

No,you cannot destroy gravity(gravitational force). But you can escape from the pull of the earth towards its centre by travelling at the earth’s escape velocity(11.2 km/s) or greater.

How do you find the gravitational attraction between two objects?

F=Gm1m2r2 , where:

1. F = gravitational force ( N )
2. G = gravitational constant ( ~6.67⋅10−11Nm2kg−2.
3. m1 and m2 = masses of objects 1 and 2 ( kg )
4. r = the distance the centre of gravities of both objects ( m )

How does distance affect 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 do you teach the gravitational force?

Put a globe in the center of the floor and tell students that gravity is pulling them towards it really really hard. One group at a time, ask them to form themselves around the globe so that they are as close to it as possible. Explain that Earth’s gravity is incredibly strong and pulls objects towards its center.

What are 3 examples of gravitational force?

Examples Of Gravity

• The force acting between the Sun and the Earth.
• The force that is responsible for the revolution to the Moon around the Earth.
• The tides that are caused in the ocean is due to the force from the Moon.
• The force that is holding all the gases in the Sun.

What is the importance of law of gravitation?

The importance of universal law of gravitation lies in the fact that it was successful in explaining many phenomena such as: how different objects in this universe affect others. how gravity is responsible for the weight of a body and keeps us on the ground. how lunar motion occurs around the earth.

What are the three laws of gravitation?

So for Newton, the force of gravity acting between the earth and any other object is directly proportional to the mass of the earth, directly proportional to the mass of the object, and inversely proportional to the square of the distance which separates the centers of the earth and the object.
