Torque is a vector quantity that has direction as well as magnitude. Turning the handle of a screwdriver clockwise and then counterclockwise will advance the screw first inward and then outward. By convention, counterclockwise torques are positive and clockwise torques are negative.
Accordingly, what does the right hand rule tell you?
The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.
What is the formula of torque?
The point where the object rotates is known as the axis of rotation. Mathematically, torque can be written as T = F * r * sin(theta), and it has units of Newton-meters. When the sum of all torques acting on an object equals zero, it is in rotational equilibrium.
Is there such a thing as negative torque?
Just pretend like it is a scalar and everything will work out fine. Oh, torque can be positive or negative. Let us say that a positive torque would make a stationary object rotate counter clockwise and a negative torque would make it rotate clockwise. If you switched these, it wouldn't really matter too much.
