Hey,
I'm taking physics as a learn-at-home kinda course to get into school for electrical. I had a question about some of the logic and reason behind what the book is showing me as it doesn't explain much. The example question they gave is as follows:
Determine the weight of a 65kg student on earth( g= 9.8m/s2 [down]).
Given - g= 9.8m/s2 [down]
m = 65kg
Required - Fg=?
Equation - Fg = mg
Solution - Fg = (65kg)(9.8ms2)
Fg = 637N
Fg = 6.4 x 102N
More or less I wanted to know why the 637N was broken up to 6.4 x 102 and how I would go about extrapolating this from every question I come across from now on.
Any info is appreciated, I am new to physics and suck at math in general...
p.s. the g's in the equation should have an arrow pointing to the right over them but I have no clue how to write that on this thing...
Thanks!
