... This force is often called the centripetal force (although it is not a real force), and the potential is called the centripetal potential. This potential is a fictitious potential and it represents the effect of the angular momentum about the origin. Figure 3 shows an example of the real potential, ...

... Problem: A 5.00-kg block is set into motion up an inclined plane with an initial speed of 8.00 m/s (Fig. P8.33). The block comes to rest after traveling 3.00m along the plane, which is inclined at an angle of 30.0° to the horizontal. For this motion determine (a) the change in the block’s kinetic e ...
