I can’t comprehend torque’s role properly:
What is torque’s nature? Is it some kind of energy? Because its unit is (N.m) and (N.m) is similar to (Joules) and it's energy unit.
As we all know “Torque” is a vector, so how can we comprehend the role of torque’s direction in the nature? I mean what’s the relation between torque’s direction and natural phenomenons involving with torque? Because as we know torque is the cross product of force and length, however why its direction is not aligned by the direction of the object’s spin? For example as in the uploaded picture, the object falls in the direction of the force while torque's direction is toward the viewer. How can we understand this in the nature and not just mathematical formulas?
