This simulation explores the concepts of net force and acceleration. Choose from one of four scenarios by clicking on its icon.

[list=1][*]Is there any difference in a force that applies a pull versus a push?[/*][*]Is it possible to apply a force and not have motion?[/*][*]What effect does friction have on motion?[/*][*]Can you determine the mass of the present in the "Motion" or "Friction" scenarios?[/*][*]In the "Acceleration" scenario, why does the surface of the water become tilted?[/*][/list][br]Credits:[br]PhET Interactive Simulations[br]University of Colorado Boulder[br]https://phet.colorado.edu
