... masses fall to the ground at the same rate? The answer to this paradox lies in the remarkable balance between the amount that gravity pulls on an object (the object’s weight) and the amount that the object inherently resists this pull (i.e., the object’s inertia). Take two objects of significantly d ...

This line is also drawn as a solid line on the outside of mirror as it moves away from the mirror surface. 2. Draw a line from the top of the ...
