Abstract

This research aims to develop a practicum tool to analyze the angular velocity and direction of rotation produced by the wheel's movement. The study method used is research and development which is the most reliable in scientific knowledge and is concerned with changes that lead to improvements. The research and development stage begins with a discussion stage for collecting ideas, submitting designs, and making tools. The working principle of the tool was to connect the tool to the electric current. So that the wheels can rotate and observe the direction of rotation. The rotation of the wheels that touch each other is connected by a rope. The data that will be obtained from this experiment is the number of turns on the wheel, the length of time the wheel rotates, and the diameter of each wheel. Data analysis was carried out by determining the frequency, angular velocity, and direction of rotation of each wheel. The result showed the intersecting wheels had different rotational directions and angular velocities. The wheel connected to the rope has a rotating direction in the same direction at different angular velocities. Thus, the practicum tool developed can analyze the angular velocity and direction of the wheel's movement rotation
