Instantaneous and Average SpeedAndrew G. BinasOliver G. FualoMa. Pearl S. MarinasJosephine D. DeteraMaryjane P. FelisminoBEED-4AEducation DepartmentSorsogon City CampusSorsogon State College, Sorsogon CityAbstractThis activity was conducted to measure the instantaneous speed of 3 runners and to determine the average speed of each. The equation v= is used to calculate the instantaneous speeds and =dT/tT is used to determine the average speed. Through which we were able to realize the relationship of the two concepts.1. INTRODUCTIONAuthentic experience can brought about lasting learning to an individual/learner. It is imperative for us to fully understand the concept of instantaneous speed and average speed so us to understand that motion is not always constant but it changes at some point, and this change has its corresponding value. And only through this authentic activity can one fully understand this conceptTo further understand this concept, one concrete example that motion is not always constant is when a person rides a tricycle. The speed of the motorcycle cant always be constant since there are factors to consider such as the safety of the passenger.
