Question

difference between the inertial and the gravitational masses

Answer 1

Inertial mass. This is mainly defined by Newton's law, the all-too-famous F = ma, which states that when a force F is applied to an object, it will accelerate proportionally, and that constant of proportion is the mass of that object. In very concrete terms, to determine the inertial mass, you apply a force of F Newtons to an object, measure the acceleration in m/s2, and F/a will give you the inertial mass m in kilograms.  

2) Gravitational mass. This is defined by the force of gravitation, which states that there is a gravitational force between any pair of objects, which is given by  

F = G m1 m2/r2  

Answer 2

inertial mass :

1)inertial mass it is the ratio between the force and the acceleration
$m = \frac{f}{a}$


2) while determining the inertial mass the body will be in motion
it is difficulty to measure inertial mass

3) it is difficulty to measure inertial mass

4) this mass changes when the velocity of a body is comparable to velocity of light



gravitational mass :
1) it is the ratio of weight of the body and acceleration due to gravity
$m = \frac{w}{g}$

2) while determining the gravitational mass the body will be at rest

3) it is easy to determine this mass as the body is at rest in a common balance

4) the mass is constant at a particular place
