LEARNING OBJECTIVES
By the end of this section, you will be able to:
Solve for the centripetal acceleration of an object moving on a circular path.
Use the equations of circular motion to find the position, velocity, and acceleration of a particle executing circular motion.
Explain the differences between centripetal acceleration and tangential acceleration resulting from nonuniform circular motion.
Evaluate centripetal and tangential acceleration in nonuniform circular motion, and find the total acceleration vector.
Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch. It is remarkable that points on these rotating objects are actually accelerating, although the rotation rate is a constant. To see this, we must analyze the motion in terms of vectors.
