Demonstrating Tangential Velocity by a Self-Coded Robot

Tangential velocity is a concept that is often taught as a part of rotation, and is the linear velocity an object has as it turns about a fixed axis. The main goal of this research project was to examine this concept and demonstrate it on a self-coded robot. The robot was designed with two rotating motors with two wings of different lengths to be attached on top, and the motors were connected to a circuit board and coded using the programming language C to rotate with equal and constant angular velocities upon initiation. The main hypothesis is that the length of rotating wings is directly proportional to the tangential velocity of the wings. The project provides a new way of demonstrating tangential velocity in a high school physics class.

Good Research

The purpose of this study is to find out how attitudes and interests of students and analyze the relationship between attitudes and student interest in high school physics subjects in Jambi Province. This type of research is quantitative which uses survey research design as a research procedure. This study involved 463 high school students in Jambi Province. The instrument used was a questionnaire with data analysis techniques namely descriptive statistics and inferential statistics. The results of the dominant student attitude indicators discussed in this paper are attitude indicators towards good research in physics with a percentage of 58.5% with a total of 271 students. The results of indicators of dominant interest are indicators of learning attention with categories good a percentage of 74.3% with total 344 students. The results of the analysis of the relationship between attitudes and interests of students towards high school physics subjects in Jambi Province showed r value 0.725 and positive. Therefore it is said that the attitudes and interests of high school students in Indonesia in physics subjects are high.

The Web

In accordance with the technological advances of web-based information delivery via the internet has more value, because the information can be delivered easily, quickly, spacious and interactive. Because this way, information is simply inserted into the web and within seconds the information can be accessed globally. Submission of this information has not been used in Ngebruk Islamic Junior High School, Sumberpucung District, Malang Regency. Submission of the information in these schools still use manual way, such as by mail, bulletin boards, or orally. Surely this way less effective and efficient, since it requires a lot of expenses such as the purchase of paper, printing machine and maintenance, ink, and its scope was limited to the scope of the school.To reduce the above problems, the delivery of information in this school need to use web media created with the PHP programming language and MySQL. PHP is a programming language that is used to allow users to process information on the web, while MySQL is the software used to store the information on the web. Once the web is run online, the school entered information to the web, can be accessed via intenet by anyone without the limited space and time
