Calculate the radius of the orbit -- the circular path the revolving object follows around another object -- by dividing the diameter by two, as shown in the formula “r=d/2,” where “d” is the diameter and “r” is the radius.
Determine the object's mass, which is the amount of matter in the object, by dividing the force acting on the object by acceleration of the object, or “m = F/a,” where "m" is the mass, "F" is the force and "a" is the acceleration of the object.
Calculate the revolving object’s moment of inertia, which is the measure of the revolving object’s resistance to movement and its angular velocity, by inserting the mass and radius of the object into the equation, “I = m*r^2,” where “I” stands for moment of inertia, “m” stands mass and “r” stands for radius. “^” is the exponent symbol, which means “to the power of.” Hence, “^2” means “to the power of 2.”
Find the object’s angular velocity by multiplying the number of rotations it makes in one minute by 360.
Calculate the object's angular momentum, L, by multiplying the object's moment of inertia you got in Step 3 with the angular velocity you calculated in Step 4. Make sure your calculated angular momentum is in units of kilograms, meters and seconds or Newton meter seconds.
Measure the charge parity of the object using the P = (-1)^L formula, where “P” is the parity and “L” is the object’s angular momentum and exponent.
