Eugene 2.0 ... i'll try explain how a computer language performs
acceleration in a narrative style.
variable definitions: a=acceleration, v=velocity, p=position
we have a loop which simple circles infinitely from start to end
if we describe a body moving at constant velocity (acceleration = 0)
then it kinda looks like this:
(start loop)
we have a loop which simple circles infinitely from start to end
if we describe a body moving at constant velocity (acceleration = 0)
then it kinda looks like this:
(start loop)
p = p + v
(end loop)
this means that the position 'p' changes each time we add velocity to it
the (end loop) returns the calculation back to the start loop
and it carries on infinitely, round and round forever
the (end loop) returns the calculation back to the start loop
and it carries on infinitely, round and round forever
so if we have starting position p =0
and velocity is 1, then each time the loop circles
it simply adds 1
so p becomes 1, then 2, then 3, etc
and velocity is 1, then each time the loop circles
it simply adds 1
so p becomes 1, then 2, then 3, etc
that is normal constant velocity
ok?
now consider this:
(start loop)
v = v + a
p = p + v
(end loop)
the velocity is now increasing each time the program loops an event
so if a = 1, the velocity increases by 1 each event
at event 1, velocity=1, position = 1
at event 2, velocity=2, position = 3
(start loop)
v = v + a
p = p + v
(end loop)
the velocity is now increasing each time the program loops an event
so if a = 1, the velocity increases by 1 each event
at event 1, velocity=1, position = 1
at event 2, velocity=2, position = 3
at event 3, velocity=3, position = 6
at event 4, velocity=4, position = 10
we can see how the ever-increasing velocity results in the position
changing at ever greater amounts
did that make sense?
(i am very patient, no need to hurry, the first steps are always hardest)
