The acceleration due to gravity on the Moon is about 1/6 that of Earth, and the mass of an object is the same on the Moon as it is on Earth. Therefore, the weight of an object on the Moon is about 1/6 of its weight on Earth.

If you're talking about mass, it's the same here and on the Moon. If you'te talking about gravity force, it's about 6x smaller on Moon than here.

<< Your mass would be 100lbs >>




<< you weight would be 16.6lbs >>



What? In the English system, weight is in pounds. However, mass is in slugs.

W = M*G

W = 100*32.2

W = 3220lbs

Where did you get 16.6??

100 pounds weighs 100 pounds on the moon. 18.65 slugs x 5.36 ft/sec^2 = 100 slugs-ft/sec^2 = 100 pounds. there's your answer.

You knew the formula to figure out weight, but you didn't know that the unit was a weight? :confused:

These people are funny. :p

Weight is actually measured in Newtons, F(g) = mg, with F(g) and g as vector quantities.

Mass is measured in pounds, kg, etc. On earth, if you mass 100 lbs, you actually &quot;weight&quot; 980 N.

Weight is a measurement of the force caused by gravitational attraction between two objects. Weight in the English system is represented as pounds, and newtons in the metric system.

Mass is a measurement of the amount of matter an object contains. Mass in the English system is represented as slugs, and grams in the metric system.

Get it right, people!

When converting between English and Metric units we often write 1 kilogram = 2.2 pounds. This is one case in science where we can blindly write down and use something that is not correct, and still probably get the answer we want! Kilograms are units of mass, and pounds are units of force. These two quantities cannot possibly be the same. It is the logical equivalent to writing down a conversion between gallons and hours!

In the Metric system, on Earth, acceleration due to gravity is 9.8 meters/sec2. So (Mass)*(Acceleration due to gravity) has the units Kilograms*meters/sec2. These units of force are known as Newtons.

In English measurement, the mass unit is the slug. And, on Earth, acceleration due to gravity is 32 feet/sec2. The force unit is, of course, the pound.
