If dark matter is matter, why is it not affected by gravity? What causes a decrease in gravitational field? What is the meaning of topple in Physics? State the factor on which the position of center of gravity of a body depends. Explain your answer with an example. ...
Text SolutionVerified by Experts The term gravity refers to the force of attraction wher one body is very often (If may be moon or any other planet) whereas the term gravitation refers to the force of attraction between any two bodies.Updated on:21/07/2023...
Um, a moon in such a complex system is not only affected by the gravitational force of the planet, but also by that of the other moons. Female student: So the planet may be pulling a moon one way, and other moons may be pulling it other ways?

The actual determination of weight might be better calculated with special consideration for the local acceleration of gravity based on altitude or latitude. Adjustments for altitude, latitude and the Earth’s radius can be factored in to show how an object will weigh more at higher latitudes than...
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...
If the density of a substance is known, to calculate the specific gravity of a substance simply divide the density of the substance by the density of water or air. Because the density of water is 1000 kg/m3or 1g/cm3, it is simple to calculate. The density of air is 1.205 kg/m3. ...
