2. Naismith's rule - Wikipedia

   en.wikipedia.org/wiki/Naismith's_rule

   Pace [6] in minutes per kilometre or mile vs. slope angle resulting from Naismith's rule [7] for basal speeds of 5 and 4 km / h. [n 1]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.

3. Velocity - Wikipedia

   en.wikipedia.org/wiki/Velocity

   At any particular time t, it can be calculated as the derivative of the position with respect to time: [2] = =. From this derivative equation, in the one-dimensional case it can be seen that the area under a velocity vs. time ( v vs. t graph) is the displacement, s .

4. Friction of distance - Wikipedia

   en.wikipedia.org/wiki/Friction_of_distance

   Spatial diffusion is the gradual spread of culture, ideas, and institutions across space over time, in which the desirability of one place adopting the traits of a separate place overcome the friction of distance. Time geography explores how human activity is affected by the constraints of movement, especially temporal costs. [11]

5. Motion graphs and derivatives - Wikipedia

   en.wikipedia.org/wiki/Motion_graphs_and_derivatives

   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 x-axis. Multiplying the velocity by the time, the time cancels out, and only displacement remains.)

6. Speed - Wikipedia

   en.wikipedia.org/wiki/Speed

   The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; [2] the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity (a vector), which indicates additionally the direction of ...
