Summary of Notation Translational motion quantities: m mass r = position vector r V = velocity ? a = acceleration F force J = linear impulse p = linear momentum Angular motion quantities: IG 0,0,0 = angular position, velocity, acceleration (2D) 3 = angular velocity (vector) .3 = angular acceleration (vector) qo moment of force about a point Qo moment of force about an axis Qo = moment of impulse about a point ho angular momentum about a point HO angular momentum about an axis = mass moment of inertia (subscript indicates about which point or axis) Subscript indicates about which point or axis Energy: V = potential energy T = kinetic energy NOTE: Plain = scalar, Bold = vector

General information: • All course resources are on Moodle: bit.ly/iamechmoo • Announcements via MS Teams • Process: • Watch lectures (Panopto videos + notes from Moodle) · Try examples papers (download from Moodle) · Try again with notes open · Chat to your supervision groups: decide what to ask supervisors · Ask your supervisors · Worked video and written solutions come out after a delay • Attend the examples class • Ask questions about the lecture notes - Moodle forum Feedback (FFF) • • The examples papers have some computing questions that use Python: don't be intimidated by them. There are instructions on what to do, and no installation is necessary: just click a link and most of the code is already completed for you! General information: • Lectures: • Watch with a friend / supervision pair / another engineer in your bubble / over MS Teams if needed (it might make the videos less boring!) - --- • The notes have been prepared with handwritten gaps (but some handwriting has already been filled in so there isn't too much to write) - - • If you have a tablet: download the "_withgaps.pdf" handouts and fill in the gaps as you watch • Don't worry if you don't have a tablet: download the "_withgaps.pdf" and follow along with your smartphone / other device. Then when you see gaps, write down the results in a blank notebook. • GAPS = KEY RESULTS / CONCEPTS IA Mechanics [F= Ma WD = D(KE+PE) [ Fat = f • Writing stuff down helps us remember things Er f = Ak • REMEMBER: the videos + completed lecture + withgaps notes are all on Moodle
