Question

DEFINE MOMENT OF INERTIA?????????​

Answer 1

Answer:

The moment of inertia, otherwise known as the mass moment of inertia, angular mass or rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration.

The moment of inertia, otherwise known as the mass moment of inertia, angular mass or rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration.

SI unit: kg m2

Other units: lbf·ft·s2

Dimension: M L2

Symbol:

Moment of inertia

Flywheels have large moments of inertia to smooth out rotational motion. This example is in a Russian museum.

Common symbols : I

SI unit : kg m2

Other units : lbf·ft·s2

Importance:

Rotational inertia is important in almost all physics problems that involve mass in rotational motion. It is used to calculate angular momentum and allows us to explain (via conservation of angular momentum) how rotational motion changes when the distribution of mass changes.

Formula:

$i \: = \frac{l}{w}$

I = inertia

L = angular momentum

w = angular velocity
