The methods that we teach students for computing with units of measurement are often not consistent with the practice of professionals. For professionals, the vast majority of computations with quantities of measure are performed within programs on electronic computers, for which an accounting for the units occurs only once, in the design of the program. Subsequent users of the program are given instructions to submit input quantities with a prescribed unit of measure, meaning submitting a dimensionless ratio of the quantity to a particular unit of measure. Likewise, users are also given instructions to interpret the numerical output as having prescribed units. Here we present a formal method for deriving both the computer code for the numerical computation, meaning the formula, and for deriving the instructions for submitting input and interpreting output. This formal method is analogous to the practice of labelling the axes of graphs with a ratio of a quantity to a unit, and treating the graph as an analogue computer for pure numbers.

“…Selama ini pembelajaran fisika tentang gerak parabola biasanya hanya membahas gerak parabola pada bidang datar tanpa gesekan udara [1] [2]. Padahal realitanya gerak parabola bisa terjadi pada bidang miring [3]. Pembelajaran tentang gerak parabola pada bidang miring tanpa gesekan udara pada umumnya tidak bisa disampaikan pada jam tatap muka karena waktu yang terbatas.…”

Generally, the learning about projectile motion on inclined surface neglecting air friction can not be delivered during the meeting hours because of the limited time. One way that can be done is by doing independent learning about projectile motion on inclined surface neglecting air friction which is assisted by an independent learning module. The purpose of this study is to design an independent learning module of projectile motion on inclined surface neglecting air friction and to investigate the effectiveness of the module toward undergraduate students’ understanding. Hopefully, this module can enrich the mechanic's modules for the undergraduate students and support them in learning about projectile motion on the inclined surface out of the meeting hours so that they can learn about the projectile motion comprehensively. The method of this study is the ADDIE model of development method consisting of Analysis, Design, Development, Implementation, and Evaluation steps. This independent learning module is applied to three freshmen of the Physics and Physics Education Department. Based on the observation sheet, the undergraduate students were able to do 88% of the module correctly, they also give 90% positive response to the statements of the module, and gets an average evaluation score of 75. Therefore, this independent learning module about projectile motion on inclined surface neglecting air friction is effective in assisting undergraduate students to understand the projectile motion on inclined surface neglecting air friction material.

“…Projectile motion has been a subject of interest to investigators for centuries. It is a common topic of physics courses today, starting with motion in a vacuum [1][2][3][4][5][6][7][8][9], through motion with linear drag [2,3], and motion with quadratic drag, the most realistic case [3,[10][11][12].…”

This paper provides the formula for the elevation angle at which a projectile has to be fired in a vacuum from a general position to hit a target at a given distance. A spreadsheet application that models the trajectory is presented, and the problem of finding the points of shot and impact of a projectile moving in a vacuum if three points of the trajectory are known is solved and modelled by another interactive application. A Gaussian elimination method is used to solve the system of linear equations that gives the trajectory parameters. These applications were developed with 30 high-school students, who were given a questionnaire to find out their opinion of the lessons.
