Gravitation is force of attraction between any two massive object of universe n cause of discovery of this force is falling down of apple 🍎 on Newton’s head. This force is attractive in Nature. According to Newton’s law of Gravitation this force is directly proportional to product of masses of two objects n inversely proportional to square of distance between them. This force can vanish when two objects will be at infinite distance apart. Force of gravity is force of attraction between Earth 🌎 n other object of universe. F = mg, where g is acceleration due to gravity.
In this chapter most important topics are escape speed, orbital velocity, Difference between gravitational potential & Gravitational potential Energy.
Numericals n derivation related to variation in g with height n depth is important.

Class 11 Physics Important Questions
Escape velocity is also very important topic escape velocity is minimum velocity with which an object is thrown from surface of earth / Planet so that it can not come back on its own n it moves out from gravitational field of that planet.
where Gravitational force can be zero?
when two masses will be at ꝏ infinite distance apart.
where g can be zero?
at center of earth because g’ = g ( 1-d/R)
When d =R then g will be zero.
Why G is known as Universal Constant of Gravitation?
Because it’s value remain same at all place. It does not change place to place.
