    2020-12-4 · To calculate torque, start multiplying the mass of the object exerting force by the acceleration due to gravity, which is 9.81. When the force is clockwise, its torque is negative, and when it’s moving counterclockwise, it’s positive. If more than one force is present, add up all the torques to get the net torque of the combined forces.
