प्रश्न
Why do children always slide down the slide and not slide up? If this slide were there in Sunita’s spacecraft, would children slide like this? Why?
उत्तर
Children always slide down the slide and not slide up because of the gravitational force of the earth. If this slide were in Sunita’s spacecraft, then children would not be able to enjoy the slide because of zero gravity in the spacecraft. and children cannot slide instead they would float.
