Formula of mass

1 answers

Yogita Ingle 7 years, 4 months ago

Mass is indestructible. As you've seen above, no matter where you are in the universe your mass will never change
Mass can never be zero. What we mean by this is that everything in the universe has mass. If it didn't it simply wouldn't exist
Mass is not related to gravity, centrifugal force, etc and these forces have no effect whatsoever on your mass
Mass is commonly measured in kilograms and grams.
m = F/a
