The correct answer is inertia. When the index card is quickly pulled away from the glass in a horizontal direction, the disk wants to keep moving in the same direction due to its inertia. However, gravity acts on the disk causing it to fall straight down into the glass.
The disk falls straight down into the glass when the index card is quickly pulled away from the glass in a horizontal direction due to the concept of inertia. Inertia is the tendency of an object to resist changes in its state of motion. When the index card is pulled away, the disk initially remains at rest due to static friction between the disk and the glass. However, once the index card is quickly removed, the static friction is overcome and the disk's inertia causes it to continue moving in a straight downward path into the glass. Therefore, the correct answer is 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 can be explained by the concept of inertia.
Inertia is the tendency of an object to resist changes in its state of motion. When the index card is quickly pulled away horizontally, the disk, which is initially at rest, wants to stay at rest due to its inertia. As a result, the disk does not immediately move with the card and falls straight down into the glass.
To demonstrate this concept, you can perform a simple experiment. Take a disk and place it on the index card. Position a glass below the card so that the disk is directly above it. Ensure that the card is holding the disk in place. Then, quickly pull the card away in a horizontal direction. You will observe that the disk falls straight down into the glass, indicating the effect of inertia.
Therefore, the correct answer to the question is inertia.
