What is the gravitational force of the moon? What is the gravitational constant on the moon? What is the gravitational force of the sun? What is a gravitational singularity? What is the gravitational force of the moon on the Earth?
What is the strength of the gravitational field on the ground just above the oil deposit? Hint: Consider the missing mass as a sphere with a negative mass. Given: a spherical oil deposit with radius 200m at a centre of depth 2.0km. The density of the Earth's crust is 2700 kg/m^3 ...
A satellite circling the earth completes each orbit in 5.10 times 10^3 s. What is the gravitational field strength at the location of the satellite's orbit? Find the speed of a satellite with a period 2 hours shorter than geosynchronous orbit. ...
A 15 kg object on the Earth is brought to the Moon. The gravitational field strength on the Earth is 10 Nkg−1−1 and on the Moon is 1.6 Nkg−1−1. What is the mass and the weight of the object on the Moon? Mass / kgWeight / N (A) 15 24 (B) 15 150 (C) 24 15...
Is 'surface gravity' the same as 'gravitational field strength'? No , it isn't . The first is gravitational field strength at the surface of the Earth . The second is a general term , that refers to the force a body exerts on a unit mass , kept at some distance , sa...
Why Mars has lower gravitational field strength than Earth? This difference in surface gravity is due to a number of factors – mass, density, and radius being the foremost. Even though Mars has almost the same land surface area as Earth, it has only half the diameter andless density than...
This is the written doomsday. The ancient books such as the Bible, through the medium of writing, wrote the scenes of the partial doomsday of the last doomsday, which was limited to the doomsday of the earth, the self-produced doomsday of the earth, not the more irresistible doomsday from...

Earth is 9.8N/kg whilst on the moon the gravitational field strength is one sixth of that.Gravitational force also keeps every object from the international space station to planets in orbit. People often think that the reason that astronauts float on the international space station is due to ...
Gravity is measured in what is called a Gravimetry and this measures the strength of a gravitational field. The instrument used to measure this is called a gravimeter, and to put it simply it measures the constant acceleration of gravity in a downward direction. ...
