Question

Explain difference between centre of mass and centre of gravity with example

Answer 1

The center of mass is the mean position of the mass in an object. Then there's the center of gravity, which isthe point where gravity appears to act. For many objects, these two points are in exactly the same place. But they're only the same when the gravitational field is uniform across an object.

Answer 2

Center of mass is the point in the body or a system of particles where the mass of the whole body seems to be concentrated. It is found by taking the weighted average position of the mass.

A body can be balanced by applying a force through the center of gravity.

Definition:

Center of mass:- it is the weighted average position of mass in a body or a system of particles.

Center of gravity:- It is the point in a body where the net torque due to gravitational forces is 0. Center of gravity is the point where the weight of the body acts
