A Matter of Some Gravity - Scores 10 - 20

@ tandjd:

You are right. I forgot my physics classes from lo, these many decades ago, and had reverted to the "everyman" sort of commonsense usage.

But technically, you are correct, so I have made the change. The figures are now in pounds (because almost nobody knows what a Newton is...)

Thanks for the correction

First of all, the kilogram (Kg) doesn't measure weight, it measures mass. In metric, weight is measured in Newtons. Mass (measured in kilograms) is not affected by gravity. The mass would be exactly the same for every planet in the solar system. If the mass is 60Kg on Earth, it would be 60Kg on Jupiter. You need to change your units to Newtons or Pounds.

Good game! I also noticed that the equatorial surface gravity for other planets seem to differ depending on where you look.

And then I revised it with information from this table:

http://en.wikipedia.org/wiki/
List_of_solar_system_objects_by_surface_gravity

The two sources differ (usually not by much), but this one is much more complete...

Much of the information here from:
