Weight
- The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms. The Newton is the SI unit for weight, and 1 Newton equals 0.225 pounds.
Gravity
- The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive.
