Inertia

The reason the disk falls straight down into the glass when the index card is quickly pulled away from the glass in a horizontal direction is due to inertia. Inertia is the tendency of an object to resist changes in its state of motion. When the index card is pulled quickly, the disk tends to stay at rest due to its inertia. However, once the index card is removed, there is no friction or force to prevent the disk from falling straight down into the glass. So, the disk falls due to the force of gravity overcoming its inertia. Therefore, the correct answer is inertia.

The disk falls straight down into the glass when the index card is quickly pulled away from the glass due to the phenomenon called inertia. Inertia is a property of matter that resists any change in its state of motion. In this scenario, the disk is initially at rest on the index card inside the glass. When the index card is quickly pulled horizontally, the card experiences a sudden acceleration. However, since the disk is initially at rest, it tends to resist this change in motion due to its inertia. As a result, the disk remains almost stationary for a moment and then falls straight down into the glass when the card is removed.

So, the correct answer is: Inertia.
