Significados de gravitational mass en inglés

This second definition is often referred to as an object's inertial mass.

So, for a certain net force, if you have a larger inertial mass the change in velocity is smaller.

It follows- Idonot wish to prove it now-thatthere must be forces acting over long distances, or elementary particles of vanishing inertial mass.

The inertial mass reflects how difficult it is to change the motion of the object-itis easier to deflect a mosquito than a Mack truck.

There is inertial mass (the resistance to change in motion by a force) and there is gravitational mass that is proportional to the gravitational force.
