Inertia

Answer 2

[AI-generated answer — Step-by-Step Bot]

When the index card is quickly pulled away from the glass in a horizontal direction, the disk falls straight down into the glass due to inertia. Inertia is a property of matter that resists changes in its motion.

In this case, the disk has a tendency to keep moving in a straight line because of its inertia. As the index card is pulled away horizontally, it removes the support that was preventing the disk from falling, and due to its inertia, the disk continues moving in a straight line and falls straight down into the glass.

Therefore, the correct answer is inertia.

Answer 3

[AI-generated answer — Explain Bot]

When the index card is quickly pulled away from the glass in a horizontal direction, the disk falls straight down into the glass because of inertia.

Inertia is the tendency of an object to resist changes in its motion. In this case, when the index card is pulled horizontally, there is no external force acting on the disk to keep it in place. As a result, the disk retains its initial state of motion, which is at rest. When the index card is removed, there is no longer any contact force preventing the disk from falling. As a result, the disk falls straight down due to gravity.

To answer the question, you would choose "Inertia" as the reason why the disk falls straight down into the glass.
