its not immediately or instant , thats why they use 1 second as the time period required for the mass to reach the acceleration rate of 1 m/s/s !!
if it was an instant acceleration then a 1kg mass could be moved a distance of 1 meter in 1 second using a force of 1N

Quote:
You don't have to wait 1 second. Even at 0.1s it's still accelerating at 1m/s/s.


ok kallog how long is 1 meters then?

and how long is 1 second then?

if 1N can imediately accelerate a 1kg mass to 1m/s/s

then why does the mass not move 1 meter in that 1 second?


f=ma

1N=1kg*1m/s/s
iv = initial velocity
fv = final velocity


velocity = iv + a*t
1m/s = 0m/s + (1m/s/s*1second)
velocity = 1m/s

avg velocity = .5 * (iv + fv)
.5 m/s = .5*(0m/s+1m/s)
avg velocity = .5 m/s

displacement = avg vel * time
.5 m = .5m/s * 1 second
displacement = .5 meters


its obvious that the mass does not move 1 meter
in 1 second so its acceleration rate might be 1m/s/s
at 1 second and after 1 second but not before 1 second.

thats why they use m/s/s

else

they would say that the definition of a newton unit of force would be.

1N is the force required to accelerate a 1kg mass instantly and continously at a acceleration rate of 1 meter per second.

even though the above would not happen in the real world
if the above were true
1N would cause a 1kg mass to move a distance of 1 meter in 1 second.

but not in reality.

instantly means as soon as the force is applied the mass would move 1 entire meter in 1 second.

but it only moves .5 meters because its not instant acceleration and that is why they use

1 meter per second^2
