This demonstration shows the independence of the horizontal and vertical components of velocity. It can also be used to introduce frames of reference. The ballistic cart propels a steel ball out of the central pipe as it moves. This means that the ball projectile and...

Almost every child at one time or another has experienced the wonder, and later, a sense of loss, from a helium balloon. The emotional attachment most students have to helium balloons can be used to focus them on a variety of Physics concepts. Adjust the...

This very simple to perform demo can be made very memorable by ensuring the students see it as a discrepant event. Students are expecting to see a free fall but instead see a low terminal velocity with no obvious source of friction.

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...
