What is an inclined plane?

An inclined plane is defined as a slanted surface that facilitates the lifting of objects to a higher elevation with less effort. This concept utilizes the principles of physics, specifically mechanical advantage, allowing a person to exert a smaller force over a longer distance to lift an object vertically. By using an inclined plane, the amount of force required to lift an object is decreased, making it easier to move heavy loads. This is commonly seen in ramps, hills, and slopes.

The other options do not accurately describe the function or definition of an inclined plane. A flat surface designed to level different grounds does not capture the essence of an inclined plane, as it lacks the slant necessary for raising objects. A machine capable of rotating at high speeds describes a different mechanism entirely, unrelated to the characteristics of an inclined plane. Lastly, a structure used for holding objects in place does not reflect the purpose of an inclined plane, which is about assisting in lifting, rather than securing objects.
