GPT-4o mini · Answer

The correct response to the question about why the disk falls straight down into the glass when the index card is quickly pulled away horizontally is Inertia.

Inertia is the property of an object to remain at rest or in uniform motion unless acted upon by a net external force. When the index card is pulled away quickly, the disk continues in its state of rest and falls straight down due to gravity since there is no upward force acting on it anymore.
