UP is a relative term. It means "further from the ground", or more exactly, "further from Earth's centre". Buckminster Fuller suggested using 'out' and 'in' for 'up' and 'down'. Presumably, people in orbiting laboratories use 'up' and 'down' relative to their floor.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
The two are related, yes, but technically it would be more accurate to say it the other way around: "Neutrons are heavier than protons because down quarks are heavier than up quarks" Neutrons are composed of an up quark and two down quarks (udd). Protons are composed of two up quarks and one down quark (uud), so the difference in mass between a proton and neutron is (roughly) the same as the difference in mass between the neutron's down quark and the proton's matching up quark. Because a down quark is heavier than an up quark, it is also possible for a down quark to decay into an up quark (releasing an electron in the process). This is how beta radiation occurs in atomic nuclei. One of the neutrons' down quarks decays into an up quark, changing that neutron into a proton, and releasing an electron (as radiation), so another way to look at it would be that a down quark is an up quark that has an electron trapped inside it (the mass of the electron, plus the energy required to "trap" it there, is what makes the down quark heavier).
The force exerted by a person on the ground is the same whether they are standing up or laying down, as it is determined by their weight. The only difference is the distribution and contact area of the force between the feet when standing versus the whole body when laying down.
Yes, there is a difference between positive and negative g-force. Positive g-force is the sensation of weight pressing down on you, like during takeoff in an airplane. Negative g-force is the sensation of weightlessness or forces pulling you away from an object, like in a roller coaster drop.

The difference between the depression and a recession is a recession is the down on an up and down rollercoaster. While the depression, there was no way to tell when it would end.
it speeds up and speeds down
A hill is hard to get up and a pill is hard to get down
A counter counts up, a timer couts down.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
One is hard up, and the other is soft down.
Dawn is when the sun is coming up, sunset is when the sun is going down
Suppressants speed your system up, while depressants slow you down.
Airplanes can not fly straight up and down or hover.
what is the difference between cut- in and cut -out
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
