Mass
Mass: The mass is the total content of the body which measures the inertia of a body. It is a scalar quantity and its SI unit is kilogram. Irrespective of the position of the body in the universe, mass always remains constant everywhere. The mass of the body cannot be zero.
Inertial mass and Gravitational mass:
Inertial mass: Inertial mass of a of a body is related to its inertia of linear motion, and is defined by newton's second law of motion.
Let a body of mass m moves with acceleration a underaction of an external force F. According to the Newton's second law of motion
The mass of the body in this sense is called as the inertial mass of the body. If a = 1, then from above equation m = F
Thus inertial mass of a body is equal to the magnitude of external force required to produce unit acceleration in the body.
Gravitational mass:
Gravitational mass of a body is related to gravitational pull of the body and is defined by Newton's law of gravitation.If a body of mass is placed on the surface of the earth of radius R and mass M,then gravitational pull on the body is given by
The mass of the body in this sense is the gravitational mass of the body. The inertia oft he body has no effect on the gravitational mass of the body.If J = 1 then from the equation
= F.
Thus gravitational mass of the body is defined as the magnitude of gravitational pull experienced by the body in gravitational field of unit intensity.

8thIt was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
Eshan Arora
8thOne of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
Aman Kumar Shrivastava
10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
Shivam Rana
7thIt has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
