A cordless mouse with an added reed switch is used as a wireless data logger to record every time the wheel of a trolley completes a revolution. The limitations of the system in terms of maximum clicking rate and spatial resolution are considered and data obtained from the descent of a trolley down a ramp at various different angles is analysed in…

Presents experiments that use Microcomputer Based Laboratory (MBL) techniques to enable freshmen physics students to investigate complex systems, such as nonlinear oscillators or coupled harmonic oscillators, at a level appropriate for an independent project. (JRH)

Describes an experiment to study the motion of a rocket-propelled vehicle over the entire duration of the engine burn using a video system with a frame-by-frame playback and a Sonic Ranger for ultrasonic position movements. Enables students to study the impulse-momentum principle and the effects of a time-varying force. (JRH)

Describes the Macintosh equipment and software necessary to obtain and use digitized video for motion analysis. Also provides a simple strategy for undertaking such an analysis. (MVL)

Presents a computer interfaced experiment that relates the equations of force equals mass times acceleration and force equals the derivative of the pressure divided by the derivative of the time. Provides setup, sample data, and equations. (MVL)

Offers free software for timing experiments, instructions for making a timing interface and a variety of switch sensors for any IBM-compatible computer, and suggestions for experiments. (AIM)

Uses a moderately priced digital multimeter that has output and software compatible with personal computers to make a portable, computer-based data-acquisition system. The system can measure voltage, current, frequency, capacitance, transistor hFE, and temperature. Describes field measures of velocity, acceleration, and temperature as function of…

Describes the use of the Texas Instruments' calculator-based laboratory (CBL) and Vernier accelerometer for measuring the vector sum of the gravitational field and the acceleration of amusement park rides. (JRH)

Studies the effect of V-Scope activities on the performance of 11th-grade students in analyzing kinematics graphs. Students were challenged to construct different kinds of graphs using their own movements as well as the motion of a dynamics cart. Results indicate that the V-Scope kinematics laboratory activities can promote kinematics concepts and…

Describes the implementation of a new microcomputer-based laboratory (MBL) curriculum focusing on motion into a physical science course for preservice elementary teachers at Indiana University. Reports the results of tests administered to teachers before and after the motions unit. Discusses implications for instruction. (LZ)

Graphs of objects in motion are frequently used in introductory high school or college physics courses since they offer a valuable alternative to verbal and algebraic descriptions by offering students another way of manipulating the developing concepts. If graphs are to be a valuable tool for students, then the level of the students' graphing…

Described is a microcomputer with two detection systems to enable three variables of the puck's motion to be recorded simultaneously: speed, radius of the orbit, and the ongoing time of measurement. Presented are the experimental setup, a discussion of the computer program, and results. (YP)

Reviews "Vernier Software: Precision Timer II" for high school through college mechanics. Introduces 14 different modes including pulse time, pendulum timer, bouncer timer, gate timer, collision timers, and stroke calibration. Provides two typical displays and ratings of the software. (YP)
