what is the difference b/w small "g" (acceleration due to gravity) & "G"(gravitational constant)?
Asked by | 19th Oct, 2013, 11:12: AM
"g" represents the acceleration of a body falling freely towards earth. It is the force of gravity acting on unit mass of a body placed on or near the surface of earth. Its value changes with altitude, depth and shape of earth.
"G" represents the force of attraction acting between two bodies each of unit mass whose centres are placed unit distance apart. Its value is constant always.
