I'm reading this question that says "The 5.5-Mg humpback whale is stuck on the shore
due to changes in the tide..."

Does Mg mean Newton?
 
Physics news on Phys.org
Nope.

Newton is [N], but Mg doesn't look like N does it? :confused:

But Mega is [M] and gram is [g]... :smile:

You're so smart :smile: thanks!
 
So according to my conversation the whale weighs

5.5 x 1000000 = 5500000grams
5500000 / 1000 = 5500 kg

5500 x 9.81 = 53955 [N]

Yes?
