★ The rate of change of momentum with respect to time of an object is directly proportional to the applied balanced force in the direction of the force.
Mathematicaly Derivation :-
Now According to Newton's second law of motion, The rate of change of momentum with respect to time of an object is directly proportional to the applied balanced force so,
Now from the formula of Acceleration we have,
Now put the praportionality constant,
Hence Derived !

★ Acceleration due to gravity ( g ) :- The Acceleration which is produced due to gravitational force who is called as Acceleration due to gravity ( g ). It's SI unit is m/s² and the value of g is 9.8 m/s² on earth.
★ Universal law of gravitation :- This law stats that Force of attraction between any two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them i.e ( F = G Mm/d² )
where G is the universal gravitational constant. It's SI unit is N m²/kg².
