If the cloud below the rocket is the exhaust, then what is that stuff coming out of the rocket engines?
The force. You know that force that requires another force to pair off?
The burn that comes out of the nozzle is the first force which expands into the dense atmosphere, which squeezes back. It creates a huge resistance in equal measures.
The cloud is the energy expended (note I said "expended") which means "exhausted" because that is the rocket exhausted fuel, meaning no more thrusting burn..
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
This is where Newtons first law is rendered useless because everything is in motion. Nothing is ever at rest.
And no, that is not trivial; it's absolutely pertinent.
As for the UNIFORM motion in a straight line, unless compelled to change its state by the action of an external force. This can only apply in your fictional vacuum. It cannot apply in an atmosphere because nothing can carry on in a uniform manner in an atmosphere, because there is always an external force resisting it, not matter how strong or weak.
This is normally taken as the definition of inertia.
This inertia comes up but inertia cannot be explained as anything. We've been through this. This is another classic case of, "it just is"...
Atmospheric pressure upon an energy force to overcome the resistance of any object.
The key point here is that if there is no net force acting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity.
Only in a fictional space vacuum, right? or are you going to deny this?
If that velocity is zero, then the object remains at rest.
Yes but it will never be at zero unless it's in a fictional vacuum, right?
The second law explains how the velocity of an object changes when it is subjected to an external force.
The law defines a force to be equal to change in momentum (mass times velocity) per change in time. Newton also developed the calculus of mathematics, and the "changes" expressed in the second law are most accurately defined in differential forms. (Calculus can also be used to determine the velocity and location variations experienced by an object subjected to an external force.) For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a:
F = m * a
For an external applied force, the change in velocity depends on the mass of the object. A force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways.
It doesn't really make any sense as any law at all.
The ISS and satellites are in a constant state of free fall due to their velocity balancing the force of earth's gravity.
Yeah, this makes absolutely no sense at all but still, even going by it, we still have the mass inside the supposed crafts as being like outside and thus, like Newy boy supposed stated. Mass upon mass will change the motion, yet the ISS always manages to never sway from it's supposed path due to mass movement inside of it by those ever exercising bad actors clanging about with weights and using the bars to chase each other in gorilla suits and such.
Never mind, eh?
What exactly do you think is going on between the air and the cars in this video?
I've already explained it.
How would you know that if you've never taken a physics class?
How do people learn to swim if they've never taken a swimming class?
How do people learn to hunt if they've never been shown?
How do people invent things of nobody's shown them?
It's called using your brain and sifting out the good from the bad and learning from mistakes, as well as making sure that bad habits are avoided, like people adhering to certain ways/traits for no other reason than trusting their peers rather than their own senses.
