Unit 2: Applications of Translation and Rotational Motion Learning Competency At the end of this lesson, the learners should be able to compare and contrast translational and rotational motion in terms of their respective linear and angular quantities Learning Targets In this lesson, you should be able to do the following: ● Define rotational motion and identify examples of objects that undergo this type of motion. ● Describe angular quantities such as angular displacement, angular velocity, and angular acceleration. ● Compare and contrast rotational motion with translational motion based on the types of quantities used to describe them. Learn About It Rotational motion is a fundamental type of movement that occurs when an object spins or turns around a fixed axis. While translational motion involves moving in a straight line, rotational motion involves spinning in place, with every point on the object following a circular path. From a rotating electric fan to the spinning Earth, rotational motion is a familiar part of our daily lives. In this lesson, we explore how to describe rotational motion using angular quantities, how these differ from linear motion, and how both types of motion are related. Basic Concepts of Rotational Motion In rotational motion, the most important element is the axis of rotation—the line around which the object turns. For example, the blades of a ceiling fan rotate around a central rod. Every point on a rotating object traces a circular path around this axis. The radius r is the straight-line distance from any point on the object to the axis of rotation. This radius 2.3. Rotational Motion 2
