if every reaction has an opposite reaction does a train stop if a fly hits it where is de opposite reaction?????????????

It just means forces are equal
F = M A
F= force
M = mass
A = acceleration
force of fly = force of train
fly has less mass than train, train has more mass than fly
M(fly,small) A(fly) = M(train, large) A(train
basic math applies and for them to be equal, the deceleration of the fly is great compared to the deceleration of the train
take in actual numbers the train's mass is about several trillion times the mass of the fly, so while the fly experiences incredible amount of deceleration the train will only expericence a small trillionth of that same deceleration
also other physics factors must also be plugged in- for example dynamic (kenetic) inertia, since the train has a large mass a great force requirement must be meet before factoring any equal forces, since the fly hitting the train doesn't have the required force to change the inertia of the train the train won't even experience that small trillionth deceleration mentioned above

When the fly hits the train or the pair of love bugs hits the windshield of your car. The resulting mess you have to clean up is the opposite reaction. Figure it out.

It does slow down, it just can't really be measured. I mean, the fly barely weighs anything, but it does work the way Newton said it does. It's like when somebody throws a ball at you while you're running. You feel it, but it doesn't stop you from running (unless it hits you in the head and you're unconscious). You vs. car is a little more equal. If a car hits you, you hit the car. The car is way huge and will at least break your knees, but you will probably break the windshield as well. You both hit each other pretty well...

Two things can happen, in order for the fly to change direction without coming to atop it must turn inside out. If it hits a soft spot a dent will occur caused by the momentary stopping of the portion of the soft spot.

force of fly vs force of train : m1a1 is very much lesser than m2a2 therefore force of train much greater than force of fly....fly go splat!
Since the mass of the fly is almost zip compared to a train's mass AND there will be a conservation of momentum, the opposite reaction is the almost zero therefore the train keeps going. Remember Newton's first law.....and the second law.....

Wow, wow, check out the other 2 Newton laws. The fly needs the same matter and speed as the train....

If you are trying to avoid learning physics by word tricks, you will get some chuckles, but you will fail nonetheless. Honestly, it's really worth learning.

The reaction would be the flies guts going everywhere.

IT WILL NOT STOP THE TRAIN....HOWEVER MANY TRAINS ARE DERAILED FOR THIS VERY REASON...THATS WHY TRAINS HAVE COWCATCHERS...YOU KNOW...GET RID OF THE COWS..THE FLIES GO WITH THEM

the reaction is splattered all over the train...beam me up scottie
