Question

State the factors on which the centre of gravity of a body depends.

State two factors on which the position of Center of Gravity of a body depends.

Answer 1

The centre of gravity of a body depends upon:

1. Body’s weight
2. Body’s shape
3. Axis of symmetry
4. Distribution of weight

Answer 2

The position of the Center of Gravity (C.G.) of a body depends on:

1. The distribution of mass in the body: The C.G. is located where the mass is more concentrated. If the mass distribution changes (e.g., by bending an object), the position of the C.G. also changes.
2. The shape or geometry of the body: The C.G. is determined by the shape of the body. For symmetrical bodies with uniform density, the C.G. is at their geometric center.
