Here Is A Question For You....

I'm sure there is some law of physics that applies here but......

If I leave a tool on the cab of my truck and drive 10 miles at 55 mph, the tool will still be on the cab unless I hit bumps and it breaks contact with the cab....because the tool is also moving at 55 mph as long as it's in contact with the cab. But during that same drive, a fly can be on the dash board and take flight inside the cab whenever it wants as if the truck is stopped. Why doesn't the back of the cab almost immediately hit the fly as soon as it takes flight?

The same physics would apply to why you can jump in the air on a plane and not end up being killed as the plane flies past you and slams you into the rear of the cabin.

 

Even if the fly isn't on the dash, it's still connected to the air in the truck that is also moving at 55mph.





The one that just splatted on your windshield wasn't... until impact.

 

I suppose so. Too bad though...I hate flies.

 

Not a fan of flies either but it's horseflies I hate...

 

We've had some huge horse flies out in the country lately. Just one of numerous things that suck about working where I work but there are plenty of great things too....like...not many people out there at all.

 

It has to do with what is called an inertial frame of reference.
Velocity is relative depending on what you compare your frame of reference to.
The plane is moving very fast to an observer on the ground, but a person inside the plane doesn't perceive that because their body is also moving at the same velocity.

Same thing with how you perceive yourself at rest right now, yet an observer in space would say that you are experiencing a rotational velocity as the earth spins on its axis.

A real fun one to consider is trains.
As you stand on the platform, a train could slowly be moving west, and let's say a person inside the train is walking east at the same velocity.

To you, it would look as though the person were walking in place.
From your frame of reference, the person has a zero net velocity because there is no differential in their position.
From the person's frame of reference, they are walking east at whatever velocity they are walking at, and of course are changing their position because they are walking to the back of the train.

 

not a fan of bar flies

 

Good answer. Thanks.

 

I can’t stand them either and they are relentless until they've taken a chunk out of you; If there are any flies I actually like it’s probably the Dragon Fly.

Dragon flies are awesome. I don't count them as flies. I actually know a bunch of nerdy, evolutionary facts about them that I'll refrain from posting. But they are very cool animals.

 

I don’t know any evolutionary facts about them but I have seen them on dinosaur murals as large as a Cessna

When I was a kid, We played down by the rail road tracks. The amtrack/personal train would flat out haul ass! I was always curious when I was young that I could jump in the car and not walk, They used to do 72mph everywhere and 80mph+ in the flats of nothing. Stupid, But as a kid I thought it would be neat if it worked!

I do know you do not have to walk out of the bed of a truck if you can time a jump and the driver hitting the throttle at the right time, You land as if you jump from a ladder. It was fun to do back in HS, My old ass would get rag dolled now most likely, Though in my mind im in my prime lol!

 

same reason that i don't jump in the air here and end up smashing into the rocky mountains.

 

If I leave a tool anywhere, anytime, it disappears and I find it in the dog kennel. Every. Time.

 

That's actually a good point.

 

truck pulls into a weigh station with a load of chickens ..
truck is overweight.
driver bangs on the walls making chickens fly in the air.
does truck weigh more or less?

 

i actually don't mind flys, if they're not walking around on me. now a fly in a box car traveling at the speed of light might be interesting.

 

Yesterday I drove to a restaurant and then on to my brother's (about 45 miles, most of it at 55+).

A Katydid rode the entire way on the hood of my car. He must have suction cup feet. I think he stayed at my brother's.
