Students will build a mouse trap powered car that converts elastic potential energy contained in the trap’s spring to linear kinetic energy of the car. The release of this energy results in a net force which leads to linear acceleration. This acceleration can be measured with Vernier Logger Pro®, and using Newton’s Second Law of Motion, the net force can be calculated. Finally, using the concept of work, the final kinetic energy of the car can be calculated. Once students become familiar with the calculation of work and energy, the teacher will challenge the students to modify their cars to …

There are only few methods available for predicting the age of cracks that are found in high
temperature structural components during service; among the promising ones is the oxide
thickness measurement technique. Oxide thickness profiles are taken from crack surfaces of
components and used for predicting the rates of crack propagation. This technique is particularly
suitable for high temperature components fabricated from ferritic steels commonly used in power
plants that run on fossil fuels. To implement this technique, it is necessary to fully understand the
kinetics of high temperature oxidation in these steels. In this study, the oxidation characteristics
of …
