1 Pg 1 Pavan s Physics SLG P + Oven = Pavan *Phys*1020* Session 1 When: M, W 7-8:30 Where: Lib 200B Words of wisdom. "Do not worry about your problems with mathematics, I assure you mine are far greater." -Einstein Agenda for this Blackhole of Space O_O Ahhh my SLG leader is a GEEK! So he is. 2 Reasons why being a geek is cool 1) You re in university we re all geeks =) 2) Geeks can do anything they want! We are all in university to learn to judge each other is a waste of our time and our potential. This is not a one-on-one tutoring session, and you will be working with each other in groups to improve each other s knowledge of the concepts that are essential to your success in this course. Inclusiveness is the only way this will work.

2 Pg 2 So let s try that again. Agenda 1) What is this SLG thinger? 2) Icebreaker get your pickaxes ready 3) Significant Figures ) Conversions I ll give you 2 pogs for 1 striker! 5) Scalar and Vector quantities 6) 1D Kinematics 7) Graphing all this mumbo jumbo SLG Rules and Procedures and Expectations 1) SLGs ARE Supercalifragilisticexpialidocious 2) I am NOT a TA. Mainly for your own sanity All sessions will be coordinated by me, but as a group we will work through the handouts and other goodies I have planned. I am a facilitator not a teacher. 3) Feel free to get up and stretch if you re butts fusing to the seat or your brain stops functioning while the sessions going on. Please, I don t like casualties. 4) Each session will consist of some type of lecture review to ensure concepts are etched into your brains more permanently. This will be done in a variety of ways but in general I am planning to have lots of exercises, and questions that I anticipate will be on the final to answer. SO bring your lecture notes and readings so we may groove with grace! 5) Learn, never Cram to ensure you can do the walk in your upper years as well. It is always better to stay on top of things rather than let them slide. I will do my best to smooth out your walk. 6) Sessions are for you, so tell me if what I have planned Is not in sync with your needs. Too Swift Too Sluggish Too Harebrained Too Boring Too Politically Correct... I will try to go for a quasi fun equilibrium. 7) Participate. You will learn more and I won t feel as awkward at the front of the room! I make mistakes I am notorious for this laugh have a good time, expect perfection, but if you think I m wrong SAY SO! (or if something doesn t make sense) Questions?

3 Pg 3 Significant Figures What is What are the number of significant figures in the following, what are the units and how would you write it in scientific form if simplified to 2 decimals? Bowls f) x 10 6 Volts b) Grapes g) X Joules c) Hz d) m/s 2 e) s Trailing zeros that aren't needed to hold the decimal point are significant. For example, 4.00 has three significant figures. (slightly confusing and ambiguous) Rules for significant figures when doing calculations BEDMAS O_o: Multiplication: Division: Subtraction: Addition: Practice = b) * 14.1 = c) * ( ) = d) ( ) * ( ) = e) / 3 = Need more practice? -coming RIGHT UP!

4 Pg 4 Conversions Profs love to throw subtle conversions at you so when you re not paying attention WHAM! You get hit with a conversion and don t realize it and your answer is wrong. The important thing is look at the units of the answer and the units of the question and let the light bulb go on! So here are a few conversions mixed up with sig. figs 1) 34.5 km/hr to m/s? Style I use to solve conversions : 2) 10 kg/hr to g/ms 3) m/s to km/hr 4) 4.5 x km/s 2 to m/s 2 5) m/s x 4.00 s (Sig figs) 6) It takes 600 ms for your eye to blink. Suppose the distance traveled by your eye is 2.3 cm. Calculate the speed your blink in m/s. 7) Find the Volume of the object with the following dimensions and keep sig figs : m, 3.05cm, km (check the text for what some of the unit prefixes mean) Slightly harder conversion: Remember 1m = 100cm» 1m 2 = 1m*1m = 100cm*100cm = 10000cm 2 etc. 8) kg / m 3 to g / cm 3

5 Pg 5 Vector vs. Scalar, definitions and all that mumbo jumbo What is a scalar quantity and give me an example. What is a vector quantity and give me an example. Distance b) 20m, 5min Displacement b) b)10m, 2min Speed b) Velocity b) Acceleration is a How exactly should you approach vector based questions to make it super easy on yourself? Let s discuss THE most important strategy!!!

6 Pg 6 Let s Talk about GRAPHS baby! Let s talk about Y and Z Here is a graph. Things to look out for: i) ii) Different graphs you ll come across Position vs. Time b) Notes Velocity vs. Time Notes Draw the motion described in the following question.

7 Pg 7 You take place in a funky camel race competition somewhere in the middle of the sahara. Your newly bought camel named Padua you know will take you to victory. You start with a constant velocity of 2.5 m/s for about 20 seconds. Some rich camel owner cuts you off and smacks your mode of transportation silly. Poor Padua decelerates at a rate of.5 m/s 2` until he comes to a rest at the finish line. After giving a 10 second pep talk you return to the starting line at a constant velocity of 1 m/s. Be sure to label a graph axis and specify units. More GRAPHS! Let s integrate those concepts

8 Pg 8 p v or v time time time Definition: Units Scalar Version Displacement Slope on Graph Area under Curve Relevant Equ Velocity Accleration Things to look forward to next session. -More graphs -1D kinematics problems -Acceleration due to Gravity -Tricks and Tips -Whatever we cover on Wednesday MIDTERM IN 23 DAYS!!! *But I m le tired.okay okay take a nap *
