Question

What is a value and unit for Gravity?

Answer 1

The gravity of Earth, which is denoted by g, refers to the acceleration that the Earth imparts to objects on or near its surface due to gravity. In SI units this acceleration is measured in metres per second squared (in symbols, m/s2 or m. s−2) or equivalently in newtons per kilogram (N/kg or N

Answer 2

hi mate,

first we want to clear

G stands for Newton's universal gravitational constant, whereas g stands for the acceleration due to gravity at a certain point. ... g = 9.8 m.s -2, g is acceleration due to gravity which is a variable quantity and a vector qualtity.

• These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2,

• where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance.

The acceleration of gravity on the surface of the earth at sea level is 9.8 m/s².
