Answer:

Weight On Venus: 22.60 kg

Step-by-step explanation:

Being that it takes the weight of an object on earth and converts it to the weight on Venus, <em><u>the formula</u></em> is Weight on Venus= (Weight on Earth/9.81m/s2) * 8.87m/s2. To find the weight on Venus, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2. This calculates the mass of the object. Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to. Being that Venus has a gravitational force of 8.87m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on Venus.

So an object or person on Venus would weigh 90.42% its weight on earth. Therefore, a person would be lighter on Venus than on earth. Conversely, a person is 9.58% heavier on earth than on Venus.

Venus is only 95% the size of Earth, and 81% of its mass. With the smaller size and mass, the force of gravity pulling you on the surface is lower. To get your weight on Venus, just multiply your current weight by 0.9. That's why 100 pounds becomes 90 pounds.
