The elevator is accelerating downwards.
If you are standing in an elevator moving up at a steady speed of 1 meter per second, your motion relative to the elevator is considered at rest. This means that you are moving along with the elevator at the same speed and direction, so you do not feel any relative motion inside the elevator.
As the elevator moves upward, the reading on the scale will temporarily increase. This is because the scale measures the force exerted by the person standing on it, which includes their weight and an additional force due to the upward acceleration of the elevator.
If the elevator is moving uniformly, the spring scale should record the same weight when it's going up as it does when it's standing still.If the elevator is accelerating (speeding up or slowing down), the spring scale will record a greater or lesser weight respectively.
If the elevator is in free fall, you and the scale would be accelerating downward at the same rate. In this case, the scale would read zero, because you and the scale are essentially falling together with the same acceleration due to gravity.
The ball's velocity changes to 0m/s and the boy's stays the same.

standing because the heart must pump blood to the whole body while fighting gravity.

A: That is a safety feature. Insure that the door is shut before elevation changes can be made. A person can be cut in half if standing on a door as elevator change elevation
Cowboys loved a colorful phrase! This meant without preparation, suddenly. The image is of you standing flat-footed with surprise.

one day I was just standing in front of a window the suddenly pellucidity through the window
Gravity maybe?
when your going up you will most likely weigh more. when you are going down you will most likely weigh less. a good example (for the going down) is skydiving while in the plane you accelerate to a certain speed and height. then you jump outside of the plane and once you jump from the plane and are in open air with nothing attaching you to the plane you are in free fall you will feel weightlessness. so on a scale that is moving the same speed as you while falling will most likely say you weigh nothing unless something is above you say the ceiling or someone else (or a huge thing everything knows as gravity) doesn't push you so as long as you don't push down on the scale while standing on top of it while the elevator is falling which i say don't do because you have to crouch onto the floor in order to survive. you will not weigh anything.

When the bus suddenly stopped, several standing riders went flying forward. I enjoy flying a kite.
