Uniform circular motion. In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. For example, any point on a propeller spinning at a constant rate is executing uniform circular motion. There are 3 possible scenarios depending on the speed of the car, $v$. The most common example of centrifugal force is the inertia experienced by an object while performing circular motion . Lesson 7: Applications of uniform circular motion, Nonuniform circular motion (Sections 5.3-5.7) Lesson 7, page 4 Problem-Solving Strategy for an Object in Nonuniform Circular Motion (page 165) 1. Consider an object which executes non-uniform circular motion, as shown in Fig. Note that we can do so either geometrically as highlighted in the video below (Note that the direction of the acceleration is towards the center) or we can determine acceleration algebraically by writing the position vector of particle in circular motion and then using $\cfrac{d^2 \overrightarrow{r}}{dt^2}$ to determine the acceleration vector $\overrightarrow{a}$, Now let’s derive the expression for centripetal acceleration algebraically.
