Laboratory sessions are highly effective in physics instruction because they provide visual, hands-on experience with relatively abstract concepts.
However, these sessions can be time-consuming and cumbersome to set up. And once an experiment is run, it is difficult to repeat it exactly to
emphasize a point or correct a misconception. This is why computer simulations are an ideal addition to any physics course or lab. Simulations offer an
opportunity to run and rerun an experiment innumerable times and to vary parameters and conditions in ways that would be impossible to duplicate in
real time.
If you are teaching mechanics this term, be sure to include Mechanics in Motion in your curriculum. Suitable as a stand-alone lecture tool or as a
complement to actual lab experiments, this simulation software covers four distinct types of two-dimensional motion: a trolley simulator demonstrates
uniform acceleration down an inclined plane; a projectile simulator highlights the factors that affect the path of an object; an air-track collision simulator
shows the conservation of momentum; and a pendulum simulator focuses on the effects of simple harmonic motion. The physics and calculations
underlying each simulation are explained in detail, and a short tutorial is offered that quickly promotes an intuitive feel for the package.
Mechanics in Motion makes it easy to visualize the effects of changing different parameters and encourages exploration in ways that real experimentation never could. It eliminates the drudgery of tedious algebraic solutions, and it produces raw data that can be automatically analyzed with graphs that underscore trends in the data. The next time you pose simple "what if?" questions in your mechanics class, make certain Mechanics in Motion is on hand to simulate the scenarios and calculate the answers. 46 pp. System requirements:
