  2. Normal force - Wikipedia

    en.wikipedia.org/wiki/Normal_force

    Figure 2: Weight (W), the frictional force (F r), and the normal force (F n) acting on a block.Weight is the product of mass (m) and the acceleration of gravity (g).In the case of an object resting upon a flat table (unlike on an incline as in Figures 1 and 2), the normal force on the object is equal but in opposite direction to the gravitational force applied on the object (or the weight of ...

  3. Anticline - Wikipedia

    en.wikipedia.org/wiki/Anticline

    They usually flank the sides of anticlines and display opposite characteristics. A syncline's oldest rock strata are in its outer limbs; the rocks become progressively younger toward its hinge. A monocline is a bend in the strata resulting in a local steepening in only one direction of dip. [ 2 ]

  4. Prone position - Wikipedia

    en.wikipedia.org/wiki/Prone_position

    Prone derives from the Latin pronus, meaning "bent forward, inclined to," from the adverbial form of the prefix pro-"forward." Both the original, literal, and the derived figurative sense were used in Latin, but the figurative is older in English.

  5. Grade (slope) - Wikipedia

    en.wikipedia.org/wiki/Grade_(slope)

    (This is the angle α opposite the "rise" side of a triangle with a right angle between vertical rise and horizontal run.) as a percentage, the formula for which is which is equivalent to the tangent of the angle of inclination times 100. In Europe and the U.S. percentage "grade" is the most commonly used figure for describing slopes.

  6. Axonometric projection - Wikipedia

    en.wikipedia.org/wiki/Axonometric_projection

    Classification of Axonometric projection and some 3D projections "Axonometry" means "to measure along the axes". In German literature, axonometry is based on Pohlke's theorem, such that the scope of axonometric projection could encompass every type of parallel projection, including not only orthographic projection (and multiview projection), but also oblique projection.

  7. Orbital inclination - Wikipedia

    en.wikipedia.org/wiki/Orbital_inclination

    An inclination of 90° is an edge-on orbit, meaning the plane of the exoplanet's orbit is parallel to the line of sight with Earth. Since the word "inclination" is used in exoplanet studies for this line-of-sight inclination, the angle between the planet's orbit and its star's rotational axis is expressed using the term the "spin-orbit angle ...

  9. Inclined plane - Wikipedia

    en.wikipedia.org/wiki/Inclined_plane

    An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load. [1] [2] [3] The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are used to move ...
