This paper is a continuation of an earlier discussion in this journal about adhering to principles of mathematics while presenting function graphs in physics. As in the previous paper, the importance of the vertical line test was examined, this paper delves more in-depth, and it pinpoints a need for presenting graphs with a continuous rate of…

Many researches show that students have difficulties in understanding graphics in kinematics. Some authors argue that we can use different instructional strategies to reduce these difficulties. Based on these studies, we developed and applied a didactic sequence using educational robotics to teach graphic analysis in movements in a dimension with…

This paper reports a computer model simulation created using Easy Java Simulation (EJS) for learners to visualize how the steady-state amplitude of a driven oscillating system varies with the frequency of the periodic driving force. The simulation shows (N = 100) identical spring-mass systems being subjected to (1) a periodic driving force of…

It is shown that the well-known Lorentz formula for time dilation can be derived from a distance-time graph plotted for a spaceship communicating with Earth.

Teaches data interpretation using the example of world running records for men and women. Explains different ways of plotting data. (YDS)

Describes a simple demonstration in which students toss crumpled paper on opposite sides of a classroom and graph the results in order to demonstrate dynamic equilibrium. (WRM)

Provides directions for constructing graphical alignment charts to solve a variety of mathematical physics problems. (MLH)

Discusses the use of logarithm and reciprocal graphs in the college physics classroom. Provides examples, such as electrical conductivity, reliability function in the Weibull model, and the Clausius-Clapeyron equation for latent heat of vaporation. Shows graphs with weighting of points. (YP)

Argues that the only reason to ask students to plot graphs manually should be to have them learn the skill of plotting graphs manually. For data-analysis purposes, the use of computer-generated graphs has several advantages and few disadvantages over manual plotting. (Author/WRM)

Discusses the uses of thermistors in teaching electronics and semiconductors. Describes how to experimentally measure and graph the characteristics of a thermistor. Suggests one possible approach to understand the shapes of the characteristics. (CW)

Described is a procedure for studying the trajectories of projectiles using ball bearings and aluminum foil. Trajectories were measured with and without the effects of air resistance. Multiflash photography was used to determine the flight paths of all objects. (KR)

Presented is a science activity which explains the discrepancies found between summer and winter solstice sunrise and sunset times. Used is a mathematical equation which takes into account the earth's changing speed and the tilt of the earth. (KR)
