Why do we lose balance when we push chair backwards while sitting on it?
Ans: All of you might have done this at some point of time. A few times some of you might have felt that they were about to fall and just managed not to fall. Why?
This brings us to a new concept called Centre of Gravity of a body. Any body or object remains in the balanced or under equilibrium till its gravitational center remains inside its circumference basis.
Center of Gravity: It’s an imaginary point in space onto which the entire mass of body can be considered to be acting. For equilibrium, this point must lie within the circumference of a body.
