If Keiji stands on his head at the park, what happens to his untucked shirt and why?
Respond very briefly.
When Keiji stands on his head, his untucked shirt will hang down towards the ground due to gravity. Gravity pulls everything towards the center of the Earth, so objects that are not secured will fall or dangle downwards. Since the shirt is loose and not fixed to Keiji's body completely, the part of the shirt that is normally hanging by his waist will fall towards his head, but it won't fall past his head onto the ground because the collar of the shirt, which is around his neck, will act as a stopping point.
