Question 6
"Frictional forces act only on objects that are moving." Is this true or false?
The right answer is the one marked above.
False — friction also acts when there is only a tendency to move. The definition covers both cases: a relative displacement that is happening, and one that is merely being attempted.
The table you pushed but could not shift is the everyday proof. Something balanced your push, and that something was friction on a stationary object.
