Ky Ly 8 years, 3 months ago

Density is a characteristic property of a substance. ... The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.

What is moment of inertia

Posted by Nancy Chhikara 8 years, 3 months ago

CBSE > Class 11 > Physics

2 answers

Ky Ly 8 years, 3 months ago

The virtue of property by which if any object will be rotate about an fixed point is known as moment of inertia. It is denoted or represented by(I) or in other words The product of the mass of the object and squre of the seperated distance is known as moment of inertia.

0Thank You

Sahdev Sharma 8 years, 3 months ago

The moment of inertia of an object is a calculated quantity for a rigid body that is undergoing rotational motion around a fixed axis. It is calculated based upon the distribution of mass within the object and the position of the axis, so the same object can have very different moment of inertia values depending upon the location and orientation of the axis of rotation.

Conceptually, moment of inertia can be thought of as representing the object's resistance to change in angular velocity, in a similar way to how mass represents a resistance to the change in velocity in non-rotational motion, under Newton's laws of motion.
