adverb / adjective
backwards
BAK-werdz/ˈbækwərdz/
In a direction opposite to normal forward movement.
The car moves backwards out of the garage, its rear emerging first.

Etymology
Back plus the directional ending makes the rear a direction of movement, rather than merely a body part. The final -s is an old adverbial ending, not a plural marker.
In context
lower the bucket to the ground and tilt it backwards just slightly this backwards tilting will raise the bucket teeth
