Where will the shadow go? what has changed? First grade.

Change your position.

The position of shadow will change with the relative relationship between light and object. When the light shines from the back, the shadow is located on the back of the object. When an object is moving, the shadow will move in the same direction, appearing in front, behind or other directions.
