Frequency—number of events per unit of time; Period—time it takes to complete one oscillation; For waves, these variables have the same basic meaning. However, it is helpful to word the definitions in a more specific way that applies directly to waves: Amplitude—distance between the resting position and the maximum displacement of the wave

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt. Created by Sal Khan.
Mission KC6 pertains to the relationship between the distance traveled, the time of travel, and the average speed. Questions involve calculations.
Average Speed Formula. The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is represented by the magnitude and does not have direction.
Active Physics Section 3 Average Speed: Following Distance and Models of Motion Learning Outcomes In this section, you will • Define and contrast average speed and instantaneous speed. • Use strobe photos, graphs, and an equation to describe speed. • Use a motion detector to measure speed. • Construct graphs of your motion.
There are several worked examples below to get you started. All of the times can be calculated based on the concept that speed = distance. time (v = d/t), or equivalently, that time = distance/speed (t = d/v). Worked Examples: 1. How much time would it take to walk to the Moon, if you could? Find: t
