Introduction to kinematics through Lagrange calculus: Discussing the concepts of average and instantaneous speed

This paper aims to introduce basic ideas about kinematics using the algebraic calculus described by Lagrange. We show that this approach is an alternative way to the usually adopted approach that uses differential calculus as a basis for discussing concepts such instantaneous and average speed.
