ELI5: What is torque?
gpt
Alright so the easiest way to get the concept of torque is to look at a loooooong pole. This pole has a certain mass and nothing will necessarily change that. However if you hold it at the center you'll notice that it is incredibly easy to balance. Now try to hold that rod at the way end while also trying to keep it balanced: this is much harder especially with a very long rod. Alternatively look at an open door. First try to open the door way at the end where the handle is: pretty easy right? Now open the door from the way base of it close to the hinge. Notice the difference in force you have to exert to shut the door? That is the torque or the rotational force of an object which gets increasingly powerful the further it is from its center or hinge.
