Answer 1

When you quickly pull the index card away from the glass, the disc falls straight down into the glass due to inertia. Inertia is the tendency of an object to resist changes to its state of motion. The disc tends to remain at rest unless acted upon by a force. Since the index card is pulled away rapidly, the disc, which was resting on the card, will not move horizontally and will fall straight down under the influence of gravity.
