Place a coin on top of a sheet of paper on a desk or table. Pull the paper horizontally with a quick snap. What concept of physics does this illustrate?

impulse = force * time = change of momentum

the key word is "quick"

rfiouh rig that is not right

This action illustrates the concept of inertia, which is a fundamental principle in physics. Inertia refers to an object's resistance to changes in its state of motion. In this scenario, the coin tends to stay at rest due to inertia when the paper is pulled horizontally with a quick snap. The coin resists the change in motion and tends to remain stationary as the paper is accelerated, eventually sliding off the edge as the friction force overcomes its inertia.

The concept of physics illustrated by this experiment is inertia.

To understand inertia, we need to know the definition - inertia is the tendency of an object to resist changes in its motion. Objects at rest tend to stay at rest, and objects in motion tend to stay in motion unless acted upon by an external force.

In the case of the coin and the paper, when the horizontal force is applied to the paper by quickly pulling it, the paper moves suddenly, but due to its low mass and flexibility, it easily moves out from under the coin. However, the coin, being more massive, tends to resist changes in its motion and remains at rest, even though the paper below it has moved. This is because the coin still experiences a weak frictional force from the paper, but it is not enough to overcome its inertia, so it stays in its original position.

This experiment demonstrates the principle of inertia by showing how the coin resists the change in motion caused by the sudden movement of the paper.
