The acceleration produced in body due to gravitational full of Earth is called acceleration due to gravity.

g=GM/r^2

Hope it helps you

✒ Accelation Due to Gravity

  • Acceleration due to gravity is the acceleration gained by an object due to gravitational force.
  • Its SI unit is m/s².
  • It has both magnitude and direction, hence, it’s a vector quantity.
  • Acceleration due to gravity is represented by g.
  • The standard value of g on the surface of the earth at sea level is 9.8 m/s².

✒ What is Gravity?

  • Gravity is the force with which earth attracts a body towards its centre.
  • Let us consider two bodies of masses ma and mb.
  • Under the application of equal forces on two bodies, the mass in terms of mass is given by :-

  • mb = ma [aA/aB] this is called an inertial mass of a body.

✒ Formula of Acceleration due to Gravity

  • Force acting on a body due to gravity is given by, f = mg
  • Where f is the force acting on the body, g is the acceleration due to gravity, m is mass of the body.
  • According to the universal law of gravitation, f = GmM/(r+h)²

✒ Symbols and Full Forms

  • f = force between two bodies,
  • G = universal gravitational constant (6.67×10^-11 Nm²/kg²)
  • m = mass of the object,
  • M = mass of the earth,
  • r = radius of the earth.
  • h = height at which the body is from the surface of the earth.
