  • What Is Torque? - Definition, Formula, Symbol,

    The unit of torque is Newton–meter (N-m). The above equation can be represented as the vector product of force and position vector. τ = r x F. So, as it is a vector product hence torque also must be a vector. Using vector product notations we can find the direction of torque. We will consider an example to see how to calculate torque.
