How can the center of mass be outside an object?

For hollow objects or a uniform ring, the centre of mass can be located outside the object. For a hollow object like the horseshoe, the centre of mass is outside. In the case of a boomerang, the centre of mass lies outside because of the asymmetrical distribution of mass because of its shape.

Can the centre of mass of a body lie where there is no mass?

Assertion : The centre of mass of a body may lie where there is no mass. Reason : Centre of mass of body is a point, where the whole mass of the body is supposed to be concentrated. Answer. For example, centre of mass of a uniform circular ring is at the centre of the ring where there is no mass.

Does the centre of mass always lie within the body?

Generally the centre of mass lies inside the body but the position may change. Centre of mass depends on the shape and its mass distribution for a continuous distributed object. The center of mass need not lie within the body.

What is concept of centre of mass?

The center of mass is a position defined relative to an object or system of objects. It is the average position of all the parts of the system, weighted according to their masses. For simple rigid objects with uniform density, the center of mass is located at the centroid.

What is the concept of centre of mass Class 12?

Centre of the mass of a body or system of a particle is defined as, a point at which the whole of the mass of the body or all the masses of a system of particles appears to be concentrated.

What is the centre of mass of a body?

What is the center of mass? The center of mass is a position defined relative to an object or system of objects. It is the average position of all the parts of the system, weighted according to their masses. For simple rigid objects with uniform density, the center of mass is located at the centroid.

Where do you think is your body’s center of mass?

The center of mass of the human body depends on the gender and the position of the limbs. In a standing posture, it is typically about 10 cm lower than the navel, near the top of the hip bones. In the anatomical position, the COG(centre of gravity) lies approximately anterior to the second sacral vertebra.

What is the concept of centre of mass?

What is centre of mass and Centre of gravity give the significance of concept of centre of mass?

Centre of mass is the point at which the distribution of mass is equal in all directions and does not depend on gravitational field. Centre of gravity is the point at which the distribution of weight is equal in all directions and it does depend on gravitational field.

Where does the centre of mass of a body lie?

Centre of mass of a body lies always at the centre of the body.

What is the advantage of the concept of centre of mass should the centre of mass of a body necessarily lie inside the body?

No it’s not necessary that the centre of mass of a body should lie inside the body. Consider a circular ring, its centre of mass lies at the center of the ring where there is no content of the body. So it can also lie outside the body .
