<![CDATA[Finding out how mass and slope affect the linear motion of dynamic trains is the goal of this investigation. To learn more about how variations in reach and tilt angle can impact an object's acceleration and speed, a variety of tests were conducted in this experiment with varying reach and tilt angle modifications. According to study findings, an object's speed and acceleration are greatly impacted by changes in its size. The object's speed increases in proportion to its mass because larger masses result in faster acceleration. The object's speed is, however, also impacted by variations in the track's inclination angle. An object moves more quickly at a larger tilt angle than it does at a smaller tilt angle. These conclusions are confirmed by calculations that demonstrate how an object's size affects its success. Further developments in this field can be based on the study's results, as they enhance our comprehension of the factors influencing linear motion in dynamic trains.]]>

<![CDATA[Material learning is a tool for conveying teaching material or messages used by an educator, where in the current era teaching media has developed and is very easy to find in other media. One of the teaching media such as E-Module, E-Module which is integrated with IMTAQ values is not often found, therefore researchers are researching this matter which has a research objective, namely for a preliminary study to see how the learning process is and what media are used during the process. learning. The method used in this research is descriptive qualitative where the researcher describes or analyzes the research results obtained. From the results of the research, researchers found that teaching media is really needed in the learning process, which can influence whether students will focus or not during the learning process, as well as whether or not the material messages that educators want to achieve in the ongoing learning process are conveyed. And the teaching media used is still PPT (Powerpoint), where researchers see that there are still many students who lack focus during the learning process, even when educators use teaching media such as PPT (Powerpoint).]]>
