All objects resist changes in their state of motion. All objects have this tendency - they have inertia. But do some objects have more of a tendency to resist changes than others? Absolutely yes! The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion? @Abhisar

How do you think this applies to the role of rotating with respect to the mass of an object?

@Abhisar ?????

OpenStudy (abhisar):

OS IS LAGGING :(

awe

OpenStudy (abhisar):

The rotational analog of mass is called as moment of inertia Moment of inertia is the mass property of a rigid body that determines the torque needed for a desired angular acceleration about an axis of rotation. Moment of inertia depends on the shape of the body and may be different around different axes of rotation. A larger moment of inertia around a given axis requires more torque to increase the rotation, or to stop the rotation, of a body about that axis.

OpenStudy (abhisar):

More the mass----->More will be moment of inertia------>More will be the tendancy of an object to resist rotational motion

YAY!

Examples of transverse wave is Light, That of longitudinal force is Sound

OpenStudy (abhisar):

*force = wave

OpenStudy (abhisar):

Transverse waves are stronger than longitudinal waves !

gotcha
