Cheat Your Physics Exam (Without Actually Cheating)

This is a really useful technique you can use to hack your physics exams. Check out this video's sponsor
In this video I look at dimensional analysis and how you can use it to get extra information out of exam questions in physics. Often the units given to you in the question tell you the equation to use, which is really useful if you have forgotten it, or if you want to check to make sure it makes sense. You are normally taught dimensional analysis to convert some units to other units, but it it useful for so much more than that!
