Hi guys,
In my head, torque has also been associated with a bare SCALAR physical quantity given by the formula ##torque=rFsin\theta## which caused a rigid body to spin around its axis.
Now, studying magnetism, I find out that torque is a VECTOR, which magnitude is indeed given by ##rFsin\theta## and with the direction of the axis and pointing upwards/downwards depending on if the body is spinning clockwise/counterclockwise.
Now, my question is: if torque let's a body spin, how could it be a vector coincident with the axis of rotation? Which physical meaning has its vectorial nature?
