3	16.1	Measuring friction. Static and dynamic friction.	If you missed the lesson, this video    explains the main concepts:  friction Lesson notes Background info videos - friction friend or foe	Watch this video as preparation for next lesson. There is no written task with this homework.
4	23.1	Resultant forces. Newton's 1st Law. Unchanging motion and steady speed or velocity.  Experiment: if you double the force on an object to move it, does it travel double the distance ?	Lesson notes	watch this video as preparation for next lesson. There is no written task with this homework.
5	30.1	The tortoise and the hare  -  'speed' Distance-time graphs Velocity time graphs   Converting units of velocity: m/s to km/h and vice versa.	Example data from the previous lesson  Usain Bolt 100m world record Kinematics of Usain Bolt's runs - detailed analysis Lesson notes If you missed the lesson,  There is a video for the lesson on this page  If you need the password, it is on the 'Terms and Conditions' sheet.  Also, this video on changing units might help you	Watch this video on recording data

7	13.2	Checking ideas from the previous lesson. Collecting data in an experiment and processing it using IT. Using googlesheets to process experimental data - averaging and graphs	Do tall people jump further ? (standing jump) Writing frame as google doc Results sheet to share Processing experimental data. Adding lines of best fit.  Using googlesheets to present data. Adding lines of best fit with Paint.	This link
8	20.2	Terminal velocity	Using googlesheets to present data. Adding lines of best fit with Paint. Example graphs to which you can add lines of best fit  Graph 1 Graph 2 Graph 3 Graph 4 Spurious data correlations Terminal velocity Galileo's ball dropping experiment On the Moon On Earth in a vacuum Sky diver and forces from freefall Video explaining forces on a parachutist    Lesson notes If you missed the lesson  then watch this video   which covers the main aspects of using google sheets for collecting data and plotting graphs.	Spend some time going through the notes, and the work you have already done. In your notebooks, write down any questions you have about the work - things you do not understand etc. We will review these next lesson.
9	27.2	Helicopter investigation	Instruction sheet Criteria - full and student friendly Writing frame (pdf) Writing frame as google doc - please save a copy or download it - do not edit the original file.	It's ski break, so no homework BUT all of you have projects on going, so if you want to spend time on these - like 20 minutes - that is fine. But this is not compulsory!
11	13.3	No lesson - Helsinki trip
12	20.3	Helicopter investigation
13	27.3	Helicopter investigation	If you have already finished, complete this task on wing shape and flying	no homework
14	3.4.	Mass and weight explain the difference between mass and weight give the correct units for mass and weight identify where a body can feel weightless and why this happens	Mass and weight; what if we grew up in space ?  Vsauce video Wet washcloth in space Flame in space g-force test pilots. Redbull races Centrifuge training Acceleration due to gravity, g.  Lesson notes	Complete this kahoot Use a sensible name, so I will know who did it. PIN code 04214539
15	10.4	Acceleration understand the unit for acceleration do simple calculations using the formula a= (change in velocity)/(time taken)	What is acceleration ? Acceleration due to gravity, g.  Calculating accelerations. Calculating accelerations video Lesson notes	Study for the open notebook test. Get your notes sorted out.
