Teaching Physics with the Physics Suite
When we drive a car we usually describe our motion in terms of a speed or velocity. A speed limit, such as 60 miles/hr, is a speed. When runners or joggers describe their motion, they often do so in terms of a pace — how long it takes to go a given distance. A 4-minute mile (or better, "4 minutes / mile") is an example of a pace.
