Question

what are the main formulas that we can use in physic, Gravitation- chapter​

Answer 1

Answer:

Explanation:

Gravitational force-

F\; = \frac{G\, m_{1}\, m_{2}}{r^{2}}

Acceleration due to gravity (g)

g=\frac{GM}{R^{2}}

Variation in 'g' with height

g'\alpha\, \frac{1}{r^{2}}

r=R+h

Variation in 'g' with depth

Gravitation- Formula- Variation in Acceleration due to gravity with depth

g'\alpha (R-d)

g'=g\left [ 1-\frac{d}{R} \right ]

Answer 2

Answer:

f g =GmM÷r^2 accelerations due to gravity
