I will ask labwork related questions

(could be theoretical or practical) in the

midterms and in the final.

COURSE OUTLINE

IMPORTANT NOTES:

Late homework or lab reports will not be accepted.

You can discuss and work together on ideas during the

preparation of your homework and lab reports.

However, direct copying of someone else’s homework or

report (including lab reports from previous years), or letting

someone directly copy your work is completely unethical, it

is plagiarism and shows you have absolutely no respect to

your colleagues or professors.

Therefore any attempt for copying in a homework or a lab

report will result in your total homework+lab grades to be

automatically zero.

WHAT IS PROPULSION ?

The word is derived from two Latin words: pro

meaning before or forwards and pellere meaning to

drive. Propulsion means to push forward or drive an

object forward.
