WebYou always have to accelerate an object toward the center of the circle to keep it moving in circular motion. If an object is moving in uniform circular motion at speed v and radius r, you can find the magnitude of the centripetal acceleration with the following equation: Because force equals mass times acceleration, F = ma, and because ... WebSep 12, 2024 · Figure 9.10.1: Finding the center of mass of a uniform hoop. We express the coordinates of a differential piece of the hoop, and then integrate around the hoop. The center of mass is calculated with Equation 9.10.1: →rCM = 1 M∫b a→rdm. We have to determine the limits of integration a and b.
