Question

5. From the definition of work, explain why only the vertical height of the stairs is measured. Hint: Think of the data table column headed “Increase of GPE."

Answer 1

The motivation behind why the vertical stature of the stairs is the main thing measured is that it uncovers to us how much gravity is up against the individual and their weight, so we require this data to decide how much vitality and power we have to get up the stairs.
