energy of a rolling object introduction In this experiment, we will apply the law of conservation of energy to objects rolling down a ramp. As an object rolls down the incline, its gravitational potential energy is converted into both translational and rotational kinetic energy.these values are and y-components of the initial velocity and will be discussed in more detail in the next part of this lesson. again, the important concept depicted in the above diagram is that the horizontal velocity remains constant during the course of the trajectory and
