A student performs an investigation by following a procedure, as shown.

The student observes that the card quickly moves out from under the coin, and the coin falls into the cup rather than moving along with the card, as shown.

Which statement explains the observation?

• An object at rest has the tendency to remain at rest.

• Inertia causes an object to change its speed and direction.

• An object maintains its position regardless of the force applied to it.
