Speed

## Summary

**Speed** is the rate at which someone or something is able to move or operate. The average speed of an object is the distance traveled by the object divided by the duration of the time interval. In other words, the formula for Speed is equal to the Distance divided by Time (D/T).

Speed is commonly referred to as "Footspeed" or "Travel Speed" on character profiles and here's a short example of what I mean:

* Example: "Speed: Average (Description)"

**Reminder**: Remember to review the notes section found under the tab titled "Explanation" as it explains some common misconceptions you must avoid doing when properly rating these types of speed.

## Footspeed

The speed at which a character, creature, or machinery can move either through power walking, jogging (referred to as the slowed, controlled form of running), or sprinting (running at top speed for a limited time).

This includes any form of acceleration of footspeed being used by the character through supernatural means or by using any engineered technology that enhances footspeed.

## Airspeed/Ground Speed

The speed of transportation, such as aircraft, amphibious vehicles (Screw-propelled vehicles and hovercraft), equestrian (horse riding), land vehicles (e.g. wagons, bicycles, unicycles, tricycles, etc.), motor vehicles (e.g. motorcycles, cars, trucks, buses, etc.), spacecraft, and watercraft or a character, creature, or machinery that is capable of bat flight, bird flight, insect flight, gliding flight, or swimming.

This includes any form of acceleration of travel speed being used by the character through ground propulsion, jet propulsion, techniques, or by using any engineered technology that enhances travel speed.

**Reminder**: As travel speed logically requires a similar reaction time in order to maneuver around incoming objects, however, certain franchises, such as Marvel Comics, DC Comics, or Image Comics (which follow the same conventions), make a great distinction between perception-reaction time (PRT) and travel speed as explained in this example here. As such, it is generally assumed that travel speed and perception-reaction time of characters is roughly equivalent to each other unless this is clearly contradicted.

## Levels of Speed

**Reminder**: For characters who are incapable of physical movement should have no Speed section and this would usually apply to any construction, machinery, and equipment, such as armor and shields, devices, items, and weaponry that lacks any function that would allow them to move.

As for characters who lack information on their speed statistics, you should rate their speed either as "**Inapplicable**", "**Average**" (as long as they are human-sized and have a humanoid physique or are giants that aren't any larger than an average building), or not add the Speed section to their character profile at all.

## Speed of Sound (**Power Walking** to **Sprinting**)

* **Subsonic** (Mach 0 to 0.72) (0-212.433434 m/s; 12.4187712003 m/s (maximum) for Humans)
	+ Faster than the Eye (FTE)/Invisible Speed: Mach 0.042090904+ or 12.4187712003 m/s+
	+ Footspeed (Sprinting): 12.4187712003 m/s
	+ Average Speed (Banana Slug): 0.000023 m/s
	+ Speed of a common snail: 0.00086 m/s (Minimum) to 0.027778 m/s (Maximum)
	+ Average Walking Speed (Humans): 1.3411200001 m/s
	+ Average Jogging Speed (Female Humans): 2.9057600001 m/s
	+ Average Jogging Speed (Male Humans): 3.7104320001 m/s
* **Transonic** (Mach 0.72-1.15) (212.433434-339.3034012511 m/s)
	+ Mach 1 = 331.2 m/s (Low-End) to 331.6 m/s (High-End)
* **Supersonic** (Mach 1.15-3)
* **High Supersonic** (Mach 3-5)
* **Hypersonic** (Mach 5-10)
* **High Hypersonic** (Mach 10-25)
* **Orbital** (Mach 25-101,608.58021)

## Time Dilation

* **Relativistic** (10%-100% **SoL**)
	+ Nearly Speed of Light (99.9998%) ~ The highest known speed measurement that light can be recorded with current technology, which would normally be impossible otherwise when doing any attempts to measure its speed at any higher percentage without the reliance of high-tech or hypothetical technology
* **Speed of Light** (**SoL**)

## Notes

Examples:
* 1. Mach 10 is High Hypersonic, not Hypersonic.
* 2. Mach 5 is Hypersonic, not High Supersonic.

* "Wormholes might allow effective superluminal (faster-than-light) travel by ensuring that **the speed of light is not exceeded locally at any time.** While traveling through a wormhole, **subluminal (slower-than-light) speeds are used.**"

Anything or any character physically traveling inside a wormhole will be limited from going any faster than the speed of light. In other words, this would be considered as an unjustifiable feat to give any travel speed ratings higher than relativistic to characters or spacecraft since they are moving between distant locations using slipstreams, therefore it would not be considered as their actual physical speed.

**Simplified Version**: No Time or Distance = Inapplicable for Speed and Speed = Undefined, therefore physical speed (the speed that can be scaled to characters) cannot be determined under these conditions.
As for timeless environments created from time stops, characters who can actively bypass the effects of time stop through sheer speed would only be rated as "**Speed of Light**" as infinite kinetic enegy always allows the character to transverse through timeless environments whereas the person who caused the time would always still move at the same speed they usually would move at without the time stop being active.

## Conversions

You can use this calculator to convert speed units.

Use this (see under section "Units") or this (see under the section "Speed or Velocity") to learn more about the in-depth knowledge of various speed units and how they are used to find speed measurements.

**Reminder:** Be sure to **always** double-check your work (no need to rush), just in case to prevent any miscalculations when inputting the measurements into the calculators that might occur as the calculations are expected to be as accurate as possible and to reduce the number of potential errors in the future.
