In your mind abstract concepts equal fantasy?
It is imaginary, right? It's an idea, right?
No, friction is not inertia. Stop saying this, nobody is saying this except you.
That's because you lot keep coming back to it. Stop using it if it has nothing to do with inertia.
Inertia is the tendency of matter to continue moving in 1 direction unless outside forces act upon it.
Friction is that outside force.
Well why do you keep saying friction is the force?
This explanation does not tell us why objects can continue to move after the force has been cut off. Why does a train keep moving forward even if the engines have been cut off?
Because it's mass displaces so much atmosphere that the atmosphere pushes right back in the equal reaction to the energetic action the train gave out.
The same as a motor boat would do on water.
Take a look at the massive wide displacement of water when a boat moves through it. All of that water still has to come right back to squeeze that boat forward and as it does, it propels the boat further through the water which creates a wide displacement again, only less and less if the power is cut.
A train does the exact same thing, as does everything else on the move.
Why is DARBEA more difficult to overcome in an upwards direction than side to side?
Stacking of atmosphere and the displacement of it by whatever object is in it.
If I was to tip you upside down and dip you in a swimming pool with a platform over your fett so your feet are pushed to the underside of the platform then asked you to jump down by using the underside of the platform to propel yourself, you would soon be pushed back up, right?
Now moving to the side you have the underside of the platform to walk along which you find easier.
Same thing happens in atmosphere, only right side up and walking the ground or using it as a springboard/leverage to push you into the stacked atmosphere that pushes/squeezes you back down.
If the atmosphere pushes us equally from all directions, why is it easier to push a car than to lift one?
You are pushing wheels against the flat ground, meaning the car has some buoyancy due to the tyres being pumped up and also creating a gap under it
This creates less friction.
Take off the wheels and try and push it. You will struggle as much as trying to lift it.
