The Socratic Method is to teach by asking questions. In the following sample problems you are guided to the solution by being asked a series of questions. If your answer is the correct one then you proceed; if it is incorrect then you are provided with a comment on your error and given another chance.

The lessons are useless if you just blindly guess and stumble through the various steps. There is ample research to show that the effectiveness of the lesson is obtained by thinking about your answer at each stage.

The problems are taken with permission from the textbook "Physics for Tomorrow's World" by E.L. McFarland and A.J. Hirsch, (Ed. 2007).

Since these lessons were written for another purpose, at the end of each problem you will see a statement "Return to Unit X". This will indicate to you that you have reached the end of the lesson. This is not a hyperlink so you will have to exit the lesson yourself by closing your browser.
