2. Naismith's rule - Wikipedia

   en.wikipedia.org/wiki/Naismith's_rule

   The original Naismith's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent. [1] [4] It is included in the last sentence of his report from a trip. [1] [8] Today it is formulated in many ways. Naismith's 1 h / 3 mi + 1 h / 2000 ft can be replaced by:

3. Foot per second - Wikipedia

   en.wikipedia.org/wiki/Foot_per_second

   The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). [1] It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). [2] The corresponding unit in the International System of Units (SI) is the meter per second.

4. Template:Math - Wikipedia

   en.wikipedia.org/wiki/Template:Math

   The math template formats mathematical formulas generated using HTML or wiki markup. (It does not accept the AMS-LaTeX markup that <math> does.) The template uses the texhtml class by default for inline text style formulas, which aims to match the size of the serif font with the surrounding sans-serif font (see below).

5. Equations for a falling body - Wikipedia

   en.wikipedia.org/wiki/Equations_for_a_falling_body

   The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 2 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 2 = 19.6 m; and so on. On the other hand, the penultimate equation becomes grossly inaccurate at great distances.

6. Motion graphs and derivatives - Wikipedia

   en.wikipedia.org/wiki/Motion_graphs_and_derivatives

   In SI, this slope or derivative is expressed in the units of meters per second per second (/, usually termed "meters per second-squared"). Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object. (Velocity is on the y-axis and time on the ...

7. Fundamental diagram of traffic flow - Wikipedia

   en.wikipedia.org/wiki/Fundamental_diagram_of...

   The graphs are two dimensional graphs. All the graphs are related by the equation “flow = speed * density”; this equation is the essential equation in traffic flow. The fundamental diagrams were derived by the plotting of field data points and giving these data points a best fit curve.
