Question 2

What's the difference between speed and velocity?

Accepted Answer

Speed measures how fast something moves (scalar). Velocity includes both speed and direction (vector). In everyday use, people often say 'speed' when technically discussing velocity.

Question 3

Why do airplanes use knots instead of mph?

Accepted Answer

Knots (nautical miles per hour) relate directly to latitude coordinates, making navigation easier. One minute of latitude equals one nautical mile, simplifying aviation and maritime calculations.

Question 4

How do I convert between meters per second and mph?

Accepted Answer

To convert m/s to mph, multiply by 2.23694. To convert mph to m/s, multiply by 0.44704. Meters per second is the SI unit used in physics and science.

Question 5

Can I use this for running pace conversions?

Accepted Answer

Yes! You can convert between pace (minutes per mile or kilometer) and speed (mph or km/h). For example, a 7-minute mile is about 8.6 mph or 13.8 km/h.

Question 6

What speed units do different countries use?

Accepted Answer

Most countries use kilometers per hour (km/h). The United States and United Kingdom primarily use miles per hour (mph). Aviation worldwide uses knots, while science uses meters per second (m/s).

Question 7

How fast is the speed of sound?

Accepted Answer

The speed of sound at sea level is approximately 343 m/s, 1,235 km/h, or 767 mph (Mach 1). This speed varies with temperature and altitude.

Question 8

What's the fastest human running speed?

Accepted Answer

Usain Bolt reached 27.8 mph (44.7 km/h) during his world record 100m sprint. Average jogging is 5-6 mph, while professional marathon runners maintain about 12-13 mph.
