Important Topics for HC Verma Solutions for Class 11 Physics Chapter 10 – Rotational Mechanics


Kinematics is a part of classical mechanics that defines the motion of points, bodies, and groups of bodies without seeing the forces that reason them to move. Kinematics is a field of education, is often mentioned as the “geometry of motion” and is sometimes seen as a division of mathematics.

Angular Momentum

Angular momentum refers to the rotational correspondent of linear momentum. It is an essential quantity in physics because it is a preserved quantity – the total angular momentum of a locked system remains continuous.

Bodies in Equilibrium

Generally, equilibrium has to do with the forces performing on a body. When no force is implied to make a body move in a line, the body is said to be in translational equilibrium; when no force is implied to make the body turn, the body is said to be in rotational equilibrium. A body in equilibrium that is not in movement is said to be in static equilibrium.

Moment of Inertia

The moment of inertia is also called as the mass moment of inertia, angular mass or rotational inertia, of an inflexible body, is a measure that defines the torque required for a preferred angular acceleration about a rotational axis; related to how mass control the force required for the desired acceleration.

Two Important Theorems on Moment of Inertia

The two important theorems on the moment of inertia include:

The parallel theorem of the moment of inertia: This law states that “Moment of inertia of any rotating body about a similar axis parallel to the axis passing through the centre of mass is equivalent to the addition of the moment of inertia about the centre of mass and product of the complete mass of the rotating body and square of the distance among two parallel axes.

The perpendicular theorem of the moment of inertia: This law states the addition of the moment of inertia of a laminar body about any two mutually perpendicular axes on the surface is equivalent to its moment of inertia about an axis perpendicular to its surface and passing through the point of intersection of the two axes.
