## Important Topics for HC Verma Solutions for Class 11 Physics Chapter 9

Centre of Mass

The centre of mass refers to a circulation of mass in space. It is the unique point where the weighted relative position of the dispersed mass sums to zero. This is the point to which a force may be imposed to cause a linear acceleration without an angular acceleration.

The motion of the Centre of Mass

The centre-of-mass is the distinct point on a structure that describes the motion of the body if the object contracts to a point mass. If a total force is applied to the centre of mass then the resulting motion will be transformation.

Rocket Propulsion

Rocket propulsion refers to the system that uses force to boost a rocket off the ground. It contains all of the portions which build up the rocket engine; the tanks pumps, powerhead, propellants, and rocket nozzle. The purpose of the propulsion system is to generate thrust. Thrust is considered as the force which transfers a rocket through the air and through space.

Collision

A collision is an occurrence in which two or more objects exert forces on each other in a comparatively short time. For example, if the matter collides and momentum and kinetic energy of the items are preserved then we call this collision “elastic collision”. On the other hand, if the momentum of the item is preserved but kinetic energy is not preserved then we call this type of collision “inelastic collision”.

Impulse and Impulsive Force

The type of forces that act for a very short period of time is known as impulse forces. The product of the impulsive force and the time it acts are termed as the impulse. The impulse is equal to the change of momentum produced by the impulsive force and can be stated as.
