Inclined Plane Experiment. Although it may seem daunting, rotational motion is fairly straightforward. In many ways it is analogous to the linear motion that you have studied previously. Rotational motion can be examined using the same principles of energy and momentum conservation that you have used previously. The equations that accompany these laws take a slightly different form, but at their root, they are based on the same physical principles. So begins your three part study of rotational motion which includes this lab, the rotating bar in . © 2016 Pearson Education, Inc.. Goals for Chapter 9 . To study angular velocity and angular acceleration.. To examine rotation with constant angular acceleration.. To understand the relationship between linear and angular quantities.. Kinetic Energy. The kinetic energy of the center of mass of an object moving through a linear distance is called translational kinetic energy. . KE = ½ mv. 2. As an object rotates it experiences a type of kinetic energy known as rotational kinetic energy.
