The purpose of this article is to use basic concepts of Newtonian mechanics, like<br \/>\ndynamics, kinetic energy and potential energy diagrams, in a scenario where the cosmological<br \/>\nconstant?s action, considered as being an inertial force driven by the accelerated expansion of the<br \/>\nUniverse, could counteract Earth?s gravity. The effect that the cosmological constant might have<br \/>\nnear the Earth?s surface is discussed showing how everyday life would change. This is done in such a<br \/>\nway that makes it accessible to students in their first year of college. Finally, the modern<br \/>\ninterpretation of the cosmological constant, associated with the existence of dark energy, is<br \/>\nbriefly discussed along with u&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The cosmological constant regained the attention of the scientific community following the recent<br \/>\ndiscovery of the accelerated expansion of the Universe.
