Thursday, Aoril 16, 2009 - Block 3

Handed back quizzes and answered any question.

Quiz on time dilation.
Expanded quiz to include length contraction. Showed how you could solve the problem either by using length contraction or the Seattle example (since the velocity was constant).

Showed how to get KE from Newton's 2nd Law.
Showed how to get E=mc^2

mc^2 = mo c^2 + KE

Do not use KE = 1/2 mv^2 for relativistic problems.

Worked problems on E=mc^2.

Went over problems 6-11 on homework sheet.

Assigned problems 12-14 for homework. This will finish up Special Relativity. We will have a test on relativity next week.
