The force used to accelerate something doesn't determine the force it can apply to something else.


yes it does.

the pipe has a constant force being applied to it.
even during the collision!!!
and when it comes in contact with something else it will apply that force to it.

if the 1000 kg pipe comes in contact with another 1000 kg
object the force of +8000N that is accelerating the 1000 kg pipe will apply itself to the other 1000 kg object.

so that both 1000 kg masses will be being accelerated by the +8000N force.

I believe that you are thinking about the momentum of the pipe , momentum isnt force.

notice that I wasnt talking about momentum , I was talking about force only.

here it is again...

theres no misconception at all.

the pipe has a mass of 1000 kg and there are 100 100kg masses being accelerated by the pipe ...

each of the 100 kg masses is being accelerated by a force of 80N

50 accelerating
50 decelerating

80N x 100 = 8000N

the pipe can apply a force of 8000N to another object.


now below you are again confussing force with momentum.

Quote:
However it can always apply a force sometime in the future, for example when it touches something. This is common sense Paul. A moving object will apply a force when it hits something.


no it cant , in order for the mass to apply a force to another object there must be a force being applied to the mass.

f=ma
its
force = mass x acceleration
not
force = mass x velocity

your talking about momentum and momentum is not force.

the mass has momentum but it has no force being applied to it.

and once again common sence cant be used as an element of an equation.

its like using the below elements in a equation.

common sence force = m*v

there no such force as common sense force.

if you dont believe me , perhaps you will believe yourself.
here is a similar situation from post # 40236 that you posted.

thats because mass x velocity is not force.
its momentum.

you said that sometimes you do a little research before you make post on the web.

maybe its a good time to do a little now before you get too confused.

correcting all of your mistakes is really getting to be a real pain.

so take a day off and do a little research.
