what is the measured force of gravity
Force is different on other planets, stars, or the moon, but on Earth's surface, 0.98N is equal to the downward force of gravity on 100 grams of mass. A person can determine the force of gravity on an object by following a mathematical formula. For instance, 1 kilogram of mass exerts a downward force equal to 9.8N. To calculate how much force gravity exerts in any particular situation, a person can use the formula f-ma, or force is equal to mass times acceleration. This can be used on animals, plants or any other object with mass.
