Question

prove that the value of acceleration due to gravity is equal to 9.8 metre per second square​

Answer 1

HEY MATE HERE IS YOUR ANSWER:-

g = MG/R^2

where g – Acceleration due to gravity

M – mass of the Earth = 5.98 x 10^24 kg  

G – Universal gravitational constant = 6.673 x 10^-11 Nm^2kg^-2  

R – Radius of the Earth = 6.38 x 10^6 m

g = (5.98 x 10^24 x 6.673 x 10^-11) / (6.38 x 10^6)^2  

g = (39.90454 x 10^13) / (40.7044 x 10^12)  

g = 0.98034954 x 10  

g = 9.8 m/s^2

Answer 2

Answer:

In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. ... A skydiver may be pulled towards earth by gravity, but they are also affected by air resistance, a force opposing their downward movement.
