Question

Why do children always slide down the slide and not slide up? If this slide where there in Sunita’s space, would children slide like this? Why?

Answer 1

Children always slide down because of gravity.
If this slide be there in space children won't slide the same way instead they would float here and there in space.

Answer 2

Due to the gravitational force by the Earth. Children usually slide down and cannot slide up. If this slide was at Sunita's spacecraft, then children would not enjoy as there is zero gravity in space and children cannot slide instead they would float.
