Answer 1

There are many possible answers. Two common objects that satisfy this criterion are escalator and temperature.

You can just stand on the first step of an escalator at the bottom and it will automatically take you to the top without you having to climb. Similarly, when you stand on the topmost step of an escalator, it will bring you down.

Similarly, you can notice the temperature in a thermometer go up and down without any movement.

Answer 2

According to me this is a very interesting riddle.In this riddle we
need to find the object that can go up
and down without moving.
We can stay that the correct answer
is "stairs".
Stairs are those object which go up and down and won't move.Thus this is the correct answer.
