When K = 0, the motion's turning points take place. Think about frictionless one-dimensional motion in the x-direction. So whenever Etotal = U, K(x) = 0 and v = 0. (x).
<h3>How to describe friction</h3>
friction is the resistance to a thing moving or rolling over another solid object. Although frictional forces can be advantageous, such as the traction required to walk without slipping, they also provide a significant amount of resistance to motion.
<h3>What leads to friction?</h3>
Because of the imperfections on the two surfaces in contact, friction is produced. Small imperfections can be found on even the smoothest surfaces, and when two surfaces interact with one another, they cause friction.

Answer:
A limestone plateau has no surface water. All the water is pulled underground through cracks and crevices in the surface. What most likely will cause the underground of the plateau to change over time?
