Chapter 11, Problem 9A

To determine

Whether the center of gravity and center of mass of an object are same.

Explanation of Solution

Introduction:

Center of mass is the point where all the mass of a body is supposed to be concentrated. The point where the entire weight of an object ishypothetically concentrated iscalled center of gravity.

If the gravitational field is uniform around an object, then both center of mass and center of gravity for an object. For uniform object, the center of gravity same as center of mass.For non- uniform objects the center of gravity and center of mass are different.

Conclusion:

Center of mass and center gravity are same for objects if they have uniform gravitational field.
