What type of mass movement occurs when rock fragments or rocks fall freely through the air?

When the rock fragments or rocks freely fall through the air, then, it is known as the rockfall. The mass movement of the rocks downwards freely when they are separated from the slope makes them slide, bounce, and roll. These rocks  may vary in their sizes from few cubic meters to multiple thousand cubic meters.

Hence, the answer is 'rockfall'.
