Which term describes motion in which the velocity of a moving object changes?

• A. Constant motion
• B. Accelerated motion
• C. Uniform motion
• D. Linear motion

Answer: (B)

The term that describes motion in which the velocity of a moving object changes is accelerated motion. This type of motion signifies that the speed, direction, or both are changing over time. When an object experiences a change in velocity, it is undergoing acceleration, whether that acceleration is due to an increase in speed, a decrease in speed (deceleration), or a change in direction.

Understanding the concept of accelerated motion is crucial in various physics applications, from analyzing the movement of vehicles to understanding projectile motion. Other types of motion, such as constant motion, uniform motion, and linear motion, imply that either speed remains constant or that the object moves in a straight line at a constant speed without any changing velocities. In contrast, accelerated motion emphasizes the dynamic nature of velocity change, making it a distinct and important concept in the study of motion.
