Friction

Occasionally, a short PowerPoint is still able to get many important facts about friction and motion across. The consequences of friction on movement and the terms used to describe it such as drag or viscosity are covered. The only missing components are some of the equations connected with this topic. Depending on the level of your class, you can easily add those with relation to the concepts displayed. The final slide gives instructions for an airplane competition; what a fun way to practice reducing air friction!
