Here's a more visceral example: pick up a brick and hold it straight

is no torque since there is no motion.

There is FORCE but no TORQUE

Ok. Change the brick out for a ski. Grasp it by the binding and hold it
vertically. Not that hard, is it?

Now grasp it by the tail and (try to) hold it horizontally. Much
harder, right?

Why? What makes one so much harder than the other? The force hasn't
increased, since the ski weighs the same as it did before.

So what makes it so much harder? HINT: torque. I double dog dare you
to hold a ski like that and tell me that you don't feel the difference.
