G. Competency/Case-Based Questions (CBQs)

The following questions are case-based. Read the case carefully and answer the questions that follow.

Motion is the change in the position of an object concerning time. Distance is the total length of path traveled by an object. Units of distance include meters, kilometers, and miles. There are different types of motion, including translational, rotational, and oscillatory. Translational motion involves movement from one point to another. Rotational motion involves movement around a fixed axis. Oscillatory motion involves repetitive back-and-forth movement. Circular motion involves movement in a circular path. Units of speed include meters per second, kilometres per hour, and miles per hour. Understanding motion and distance is crucial in physics and engineering to describe and analyze the world around us.
