According to Newton's Second Law of Motion, force is equal to the product of mass and gravitational acceleration. The formula is F=mg. Because weight is also a force, you can calculate the mass of everyday objects by using the same formula.
Continue ReadingUse an accurate balance to find the weight of the object. Use beam balances for small objects and spring balances for larger ones.
If you find more than one weight, take the average to minimize errors in the final reading.
Insert the weight value in the place of "F" in the formula to provide the force. Use 9.81 m/s^2 as the value of gravitational acceleration. Divide "F" by "g" to find the mass of the object.
