Question

all formules which are in chapter 1 gravitation std 10 ssc​

Answer 1

1. gravitational force = (gravitationalconstant)(massofobject1)(massofobject2)/(distancebetweenobjects)2

Fg = Gm1m2/r2

2.

Answer 2

Answer:

Newton's law of gravitation

m1m2

F = G. _____

d²

F = ma

Kinematical equations

1) v = u + at

2) s = ut + ½ at²

3) v² = u² + 2as

Important values

1) G = 6.67 × 10‐¹¹ Nm² / kg²

2) Mass of Earth = 6 × 10²⁴kg

3) Radius of Earth = 6.4 × 10⁶m

● Acceleration due to gravity

GM

g =

R²

Weight

W = F = mg

W = F = GMm

R²

● Kinematical equations

v = u + at

s = ut + ½ at²

v² = u² + 2as

● Important Values

1) On Earth g = 9.77 m/s²

2) On moon g. = 1.63m/s²

m

● Escape velocity

V esc = Under root 2gR

● Kepler ' s law

T² = k

R³

Important note

1. Downward g is positive = 9.8 m/s²

2. Upward g is negative = – 9.8 m/s²

Explanation:

I hope this formula is helpful for you
