Keeping this in view, how is G value calculated?

To **calculate** the force of gravity of anobject,use the formula: force of gravity = mg, where m is the massof theobject and **g** is the acceleration of the object duetogravity. Since **g** is always 9.8 m/s^2, just multiplytheobject's mass by 9.8 and you'll get its forceofgravity!

Likewise, what is the unit of G? **G**isthe universal gravitation constant, aka Newton's constant. Itisapproximately6.674×10−11m3⋅kg−1⋅s−2. **g**is the acceleration dueto gravity, and is approximately 9.81m⋅s−2. On theother hand, if you mean what do **G**and **g** mean in SI,**G** is a prefix meaning 10^9, and isspelt Giga.

Considering this, who found the value of G?

Cavendish

What is Big G in physics?

The gravitational constant, called in**physics**equations, is an empirical physical constant. It isused to showthe force between two objects caused by gravity. Thegravitationalconstant appears in Isaac Newton's universal law ofgravitation. isabout6.67430×10^{−}^{11}N⋅m^{2}/kg^{2},and is denoted by letter.
