lift
It will always be a force, just as lon as you are pushing or pulling it up!
'It's called Tension
Gravity . . . pulling you down. The scale . . . pushing you up. If these two forces were not equal, then there would be a net force on the bottom of your feet, either upward or downward, and you would be accelerating.
In my case, the magnitude of the force is 195 pounds. In return, I am also pulling the Earth up toward me with a force of 195 pounds.
Because there is an equal and opposite force pulling you down: gravity.
lift
the force used to push the object up the plane.

Up
'It's called Tension
the resistance force is the slope of the plane, or the hypotenuse.

Normal force is the force of a surface acting on an object( the normal force is perpendicular to the plane of contact). This force is directly related to the force of gravity, as the third law of newton state that when a force is applied to an object it will react with an equal force in the opposite direction. So when an object is placed on a surface, the force of gravity is acting on it (pulling it down), but the is object remain in place due to the normal force (which is pulling up on the object). In addition, a change to the force of gravity will result in the same change to the force of normal, to allow an object to remain stationary.
It really depends. The spring; whatever is holding the forcemeter up; the normal force of the earth pushing up on what's holding the force meter up... depends on your reference frame

Think of a heavy box lying on the ground with a rope attached for pulling. Until you try to pull the box it doesn't actually resist you. Once you start pulling on the rope, and even if you are unable to move the box, it is as if there is a force pulling against you. This is the force of friction. The friction between the box and the ground sets up this force.
