प्रश्न
State two factors on which the position of center of gravity of a body depends.
Advertisements
उत्तर १
The centre of gravity of a body depends upon:
- Body’s weight
- Body’s shape
- Axis of symmetry
- Distribution of weight
उत्तर २
The position of the center of gravity of a body depends on:
- The distribution of mass in the body: The center of gravity 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.
- The shape or geometry of the body: The center of gravity is determined by the shape of the body. For symmetrical bodies with uniform density, the C.G. is at their geometric center.
Notes
