study the entries in the following table and rewrite them putting the corrected items in a single row :gravitation

Answer:

Reasons

• Mass is the amount of matter in a body. Its SI unit is the kilogram, and it is a measure of inertia.
• Weight is the force with which the earth attracts a body, \(W = mg\), so its unit is the newton. Since \(g\) changes with height, the weight of a body depends on its height above the earth's surface.
• Acceleration due to gravity has the unit m/s². It decreases as we go deeper inside the earth and becomes zero at the centre of the earth.
• G has the unit N m²/kg² and the same value, \(6.67\times10^{-11}\ \mathrm{N\,m^2/kg^2}\), everywhere in the universe.

(Strictly, weight is also zero at the centre and g also depends on height, so the last column of these two rows can be paired either way; the pairing above is the one commonly used for this textbook question.)
