Does it take more energy to slide a crate over a tile floor or a shag carpet

From my experience, it is more difficult to slide a crate on a shag carpet because of the material the carpet is made out of. When it is a tile floor it will just slide with ease.

Explanation:

wood carving remains today the primary sculptural art form of the sub saharan continent. african art history shows the earliest wooden sculptures from the 17th c are attributed to the kuba, central zaire but the earliest surviving sub-saharan sculpture is a zoomorphic head found in 1928 in central angola.

i hope this .
