Gravity: Did You Know? Gravity Varies Across Earth's Surface The force of gravity is not the same everywhere on Earth. It is slightly weaker at the equator due to the centrifugal force caused by Earth's rotation and the fact that the Earth is not a perfect sphere but an oblate spheroid...
After knowing what is gravity, let us have a look at a few examples of gravity at work are: The gases in the sun are held together by gravity. Gravity is responsible for water resting at the bottom of a glass instead of hovering over at the top. The force of attraction between the ...

To summarize, according to Einstein, gravity is the curving of spacetime by all the objects in it, combined with the "geodesic" (straight) motions of those objects through the spacetime. A good analogy to help you think about this is to imagine a rubber sheet stretched taut in a frame, ...
Solution Verified by Toppr The earth attracts (or pulls) all the objects towards its centre. The force with which the earth pulls the objects towards it is called the gravitational force of the earth or gravity. Was this answer helpful? 3Similar Questions Q1 What is gravity ? View Solution ...
The standard gravity measurement was established in 1901 at the third Conférence Génèrale des Poids et Mesures (CGPM). The CGPM world conference met in 1901 to clarify the definitions of mass versus weight. The first conference commenced in 1889 in Paris and reconvenes every four years to auth...
Gravity perplexes scientists in other ways, too. TheStandard Model of particle physics, which describes the actions of almost all known particles and forces, leaves out gravity. While light is carried by a particle called a photon, physicists have no idea if there is an equivalent particle for...
Why is acceleration due to gravity the same for all objects? Although the gravitational pull of the earth on both objects is different, so is their mass. So, the effect that we see, or acceleration, is the same. The earth’s pull makes the objects speed up by 9.8 meters per second, ...
In the same manner, an astronaut is in free fall under the Earth's gravity but is also moving so fast forward that during the time he's fallen a foot, he's moved far enough forward that the curvature of the Earth has dropped a foot below him. For every foot he moves toward the ea...
You would probably think the heavier one would fall faster because of Gravity, but it is false. You would need to factor in drag and air resistance when experimenting, and you could not compare the dropping of a piece of paper with a pen as the paper has more size and is affected by ...
