Which is not a “big idea” involving force and motion?

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

The substances that are necessary for producing of certain hormones and that store and transport vitamins

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
