The rotating or turning force applied to an object like a bolt nut is called torque.

Here's why:

* Force is a push or pull on an object.

* Torque is a twisting force that causes an object to rotate around an axis.

When you use a wrench to tighten a bolt, you're applying a force to the wrench handle, but the actual force causing the bolt to turn is torque. This torque is calculated by multiplying the force you apply by the distance from the axis of rotation (the center of the bolt) to the point where you apply the force (the end of the wrench handle).

So, while you might think of it as a rotating force, it's more accurately described as torque, the force that causes rotation.
