OK

so N*seconds = N

Quote:
4000N * 1 second = 4000N


80N * 50 seconds = 4000N

Quote:
4000Ns * 1 second = 4000Ns^2 which is not impulse


Quote:
the force that accelerated each of the 100 kg masses
was +80N x 1000 meters = +4000N


Quote:
No. That quantity is 80,000Nm. Nm is not force. Actually it's energy.


Quote:
LOL

your right , I did mess that up.

it is +80N applied for 50 seconds.

+80N each second for 50 seconds over a distance of 1000 meters

+80N x 50 seconds = +4000N


Quote:
4000Ns, not 4000N. This is the impulse applied to the pipe, not the force. It's also the momentum added to it.

what comes around goes around!

I have my second opinion now.

if a force of 4000N is applied for 1 second
you would have applied a total force of
4000N for that 1 second.

4000N * 1 second = 4000N

the total force doesnt change just because you apply it.

but you can apply the total force over several seconds

2000N * 2 seconds = 4000N

80N * 50 seconds = 4000N

1N * 4000 seconds = 4000N

4000N is the total amount of force required to accelerate a 100kg mass
to an acceleration rate of .8 m/s/s
over a distance of 1000 meters
in 50 seconds

the 100kg mass will then have a velocity of 40 m/s
its momentum is
100kg * 40m/s = 4000Ns

1N is the total amount of force required to accelerate a 1kg mass
to an acceleration rate of 1 m/s/s
over a distance of .5 meters
in 1 second

the 1kg mass will then have a velocity of 1 m/s
its momentum is
1kg * 1m/s = 1Ns



3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
