An object at rest stays at rest
and an object in motion stays in motion
with the same speed and in the same direction
unless acted upon by an unbalanced force.
How can it be applied today?
I use THAT
one every day!
I got good at it; practice makes perfect.
I do it by remaining in the same place, in front of my computer
and also in front of my TV, for several hours at a time, proving it and re-proving it,
to make sure that he got it right. It seems to be working out OK, so far.
