Most of us know from experience that the force of friction caused by air resistance increases as the relative speeds increases. The purpose of this activity is to develop a proportionality statement, and then an equation, that describes the relationship between air...

A head on elastic collision between an object with mass M and an object with mass 3M traveling with equal speeds results in all the kinetic energy of the system being transferred to the smaller mass. In this demonstration we try to follow this arrangement to produce a...

If equilibrium is to be achieved, opposing reactions must take place in a closed system at the same rate. The two reactions, known as forward and reverse reactions, shown by a general reaction such as: A + B C When the forward and reverse reactions are taking place at...
