Answer :
Children go up the hill in a zigzag pattern because it requires less physical effort and optimizes the climb time.
Why does it happen?
- When climbing the hill in a straight line, children need to exert greater physical effort.
- The straight-line ascent makes children have to move against gravity.
- Gravity pushes children's bodies downwards, requiring them to exert more effort to move upwards.
When climbing the hill in a zigzag, children do not move directly against gravity, but they can suffer less impact and less physical effort to move since the impact of gravity is less.
In this case, children can move faster and climb with less effort.
