One only has to have faith if you understand the distinction, but do not
"Perhaps it is better to define mass as: what a beam balance measures

but that's only 1/2 of it as others have written. What is impt. (I
pray.) is that, as one mentioned, both are the same #. Why was an
accident until Einstein "said" they had to be the same * . We've
already had a thread(s) on Eötvös.
Just one of the things HS students must believe (have faith). That
shouldn't be difficult as so many believe in much more outrageous things.

What is the name given to the resistance observed when attempting tochange
the direction of a moving object which is otherwise perfectly free tomove?
When push comes to shove I tell my students that mass like charge isI realize it may be difficult to swallow in the physics paradigm, but
something that "stuff" has.

the
description given above is in fact, adequate.
To change direction is to impart a change of speed in some direction
