Would the springs inside a bathroom scale be more compressed or less compressed if you weighed yourself in an elevator that moved upward at constant velocity?

While you're moving up or down at constant speed, the situation is exactly
the same as standing on the ground. The scale reads your weight, and the
springs are in the same condition as they are when the scale is on the floor
of your bathroom.
-- During the brief few seconds when you're accelerating downward ... starting
down from an upper floor or stopping your ascent at an upper floor ... your weight
temporarily seems to be decreased, and the springs are less compressed.
-- During the brief few seconds when you're accelerating upward ... starting up
from a low floor or stopping your descent at a low floor ... your weight temporarily
seems to be increased, and the springs are more compressed.

What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
Can you go around a curve with constant velocity?
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
Why might an elevator cable break during acceleration when lifting a lighter load than it normally supports at rest or at constant velocity?
If it was really old or moldy and wet.
Why areal velocity is constant in central force?
If the force is constant then this will make the velocity of the object spinning constant as well, and for the velocity to be constant all the forces must be balanced and therefore constant
When elevator move down with acceleration pendulum of bob what is effect on time period?
When the elevator starts moving down, the time period increases. But when the elevator is descending at a constant velocity, the time period returns to its normal.
Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
What is your acceleration if you have a constant velocity?
If your velocity is constant, then your acceleration is zero.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
A cable lifts a 1380-kg elevator at a constant velocity for a distance of 29 m What is the work done by each What?
Velocity not changing....so kinetic energy remains constant..only potential energy is changing....the work done is therefore....(mgh=1380*29*9.8J)=(392196J)

If you have a constant velocity do you have to have a constant speed?
Yes, speed is the scalar of velocity.
Why areal velocity is constant in central force?
If the force is constant then this will make the velocity of the object spinning constant as well, and for the velocity to be constant all the forces must be balanced and therefore constant
What is constant velocity in terms of physics?
Constant velocity means constant speed in a straight line.
Why might an elevator cable break during acceleration when lifting a lighter load than it normally supports at rest or at constant velocity?
If it was really old or moldy and wet.
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
