“…This shows that displacement and time have a value that is directly proportional so that the graphic form of uniform linear motion is in the form of a linear line. The graph of uniformly changing linear motion shows the motion of an object on a linear trajectory with an acceleration that increases regularly or experiences constant acceleration, a graph of uniformly changing linear motion experiences acceleration because the curve opens upwards so that the graph of uniformly changing linear motion is in the form of a parabola [20].…”

Experimental activities aim to improve understanding and thinking skills in understanding physics concepts. But in reality, the experiment has not been carried out properly, due to the use of manual instruments so it affects the results of the linear motion experiment obtained. As a solution to the problem, namely by making a linear motion experimental modeling tool assisted by a toy car with speed control for video tracker analysis. The purpose of this study is to determine the performance specifications of the linear motion experimental modeling tool, the accuracy and precision of the time measurement on the linear motion experimental modeling tool, to determine the effect of the relationship between physical quantities on the linear motion. The type of research conducted in engineering research. The data analysis technique used is descriptive data analysis and error analysis. From the data analysis, it can be stated three results of this research. First, the performance specifications of the linear motion experimental modeling tool consist of toy cars measuring 13x7 cm, controlling the dc motor using a step-down xl-6009 dc-dc, measuring angles using mpu6050, trajectory measuring 2.0x0.10 m, processing experimental results using tracking software. Second, the average accuracy of time measurement in LMCV is 98.16% with an average error of 1.93%. The average accuracy of time measurement in LMCV is 98.38% with an average error of 1.53%. Third, the velocity value obtained is proportional to the applied voltage value, while the acceleration value is proportional to the increase in the angle used.

“…Each point from the hamster's motion interprets the displacement of its position. Prihatini et al (2017) explain that a change in the position of an object indicates the direction of increasing the number of coordinates, namely the right direction in the form of a positive direction and the direction to the left in the form of a negative direction. Table 1 shows that the direction of the middle of the body and the hind legs is to the left so that the direction shows a negative vector quantity.…”

This study aims to explain the phenomenon of motion in hamsters moving in a rolling wheel. Motion is one of the materials taught at the 7th-grade junior high school. The study can be used in learning with the practicum method, namely animal motion. Hamster (Cricetinae) motion is analyzed using a video tracker analysis application with a javascript program. This study used a direct experiment using a hamster using four reference points, namely the forelegs, head, middle body, and hind legs. The results of data analysis from the tracker application were processed using the Microsoft Excel program to obtain a graph of changes in the position and velocity of the hamster. Hamster motion on the rolling wheel is a type of translational motion, namely uniform linear motion. Changes in the hamster's position indicate motion on a horizontal line. The velocity obtained in the tracker application is more accurate than manual calculations.

“…Regular Changing Straight Motion is motion whose trajectory is in the form of a straight line with its speed changing regularly and has a fixed acceleration. Regular Changing Straight Motion (GLBB) is the motion of particles on a straight-line trajectory with a fixed direction of motion that travels a distance that changes regularly every one unit of time (Prihatini et al, 2017).…”

The purpose of the study entitled Needs Analysis of Learning Media Development Exe Learning Straight Motion Material Changes Regularly for Senior High School Class XI is to conduct a needs analysis to find out how much students and teachers need to develop E-module learning media based on the Exe learning application on Straight Motion Changing Regular Class XI material. The method used is the qualitative descriptive method. Data collection techniques carried out in this study were carried out by observation and interview activities. The instruments used are the observation data collection technique using an observation sheet instrument and when the interview data collection technique uses an instrument, namely an interview sheet consisting of teacher interview sheets and student interview sheets. From the research conducted, it was found that the understanding of student concepts at SMA Negeri 1 Kota Bengkulu, SMA Negeri 3 Kota Bengkulu, and SMA Negeri 9 Kota Bengkulu still needs to be improved, especially in the subject of physics of Straight Motion Changing Regular material. This is due to learning media that is still not interesting. Based on the results of the needs analysis conducted for the development of E-modules for Class XI Physics Regular Changing Straight Motion material, it can be concluded that teachers and students at SMA Negeri 1 Kota Bengkulu, SMA Negeri 3 Kota Bengkulu, and SMA Negeri 9 Kota Bengkulu still need the development of E-modules to improve students' understanding of concepts.
