Is gravity stronger at the surface?
Since gravity is inversely proportional to the square of the distance, a space station 400 km above the Earth feels almost the same gravitational force as we do on the Earth’s surface….Relationship of surface gravity to mass and radius.

What is the surface gravity of Earth?
9.807 m/s²
Earth/Gravity
The precise strength of Earth’s gravity varies depending on location. The nominal “average” value at the Earth’s surface, known as standard gravity is, by definition, 9.80665 m/s2 (about 32.1740 ft/s2).
How do you find surface gravity?
The acceleration that a body experiences on the surface of a planet, the gravity on surface, depends on the mass M and radius R according to a simple formula of Newton’s: a=GM/R2, in which G denotes the universal gravitational constant.
Is gravitational and gravity the same?
Generally, people consider these two as the same term. Although these two sound alike, there is a difference between the two. Gravitation is the force acting between two bodies While, gravity is the force between an object and the earth’s surface.
Where is gravity weakest on earth?
the equator
The force of gravity is weakest at the equator because of the centrifugal force caused by the Earth’s rotation and because points on the equator are furthest from the center of the Earth.
What is meant by surface gravity?
Definition of surface gravity : intensity of the force of gravity at the surface of the earth or a celestial body.
Do stars have gravity?
A star is a sphere of gas held together by its own gravity. The closest star to Earth is our very own Sun, so we have an example nearby that astronomers can study in detail. The lessons we learn about the Sun can be applied to other stars. A star’s life is a constant struggle against the force of gravity.
What is difference between acceleration due to gravity and gravity?
‘G’ is a constant appearing in Newton’s law of gravitation. Newton’s law of gravitation is given as: F=G⋅m1⋅m2r2. Whereas ‘g’ is the acceleration of a body freely falling under the influence of the force of gravity. Use Newton’s second law of motion to obtain acceleration due to gravity ‘g’.
