Question

which simple machine is a slanted surface that helps move objects to a higher or lower place?
inclined plane
screw
wedge
lever

Explanation:

To determine the correct simple machine, we analyze each option:

• Inclined Plane: Defined as a slanted surface (ramp) used to move objects between different heights, matching the description.
• Screw: A helical inclined plane, but its primary function is not just moving objects to higher/lower places via a slanted surface in the basic sense described.
• Wedge: Used for splitting or holding, not primarily for moving objects to different heights with a slanted surface.
• Lever: Uses a fulcrum to lift, not a slanted surface.

Answer:

A. Inclined Plane
