Help! 8th grade Physics test tomorrow. I need the answers!
-
When the object is stationary.
-
Assuming you're pushing the object parallel to the surface, friction is greatest when the object's velocity is constant. In other words, if the object's velocity v = c (c is constant), the friction it experiences is greatest.
-
When the object that the friction is acting upon is stationary
-
when there is no grease.
