Question

All the formulas for chapter gravitation [physics] (class 9)

Answer 1

F=GMm/r^2
r^3/T^2=constant
F=mg
g=GM/R^2
W=mg
P=F/A
Density = m/v
Pressure =h*density*g
Bouyant force= v*density*g

Answer 2

Answer:

$f = \frac{m \times m}{d {}^{2} } \\ mg = g \frac{m \times m}{ {r}^{2} } \\ g = g \frac{m}{ {r}^{2} } \\ v = u + at \\ s = ut + \frac{1}{2}at \\ {v}^{2} + 2as \\ f = m \times a \: that \: is \: f = m \times g \\ {w}^{m} = g \frac{ {m}^{m} \times m }{ {r}^{2} \: m } \\ pressure = \frac{thrust}{area} \\ relative = \frac{density \: of \: a \: substance}{density \: of \: water}$
