Investigation crimes video
40	Paper helicopters investigation		Lesson notes Friday group
41	Paper helicopters investigation			If you have not yet completed your purpose, apparatus, plan/method and variables section these must be done.
42	Completing the investigations	The idea is to finish the investigation this lesson	If you have finished the investigation then do this task:  this task on wing shape and flying	No homework if you have finished the investigation
44	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; Red bull races and g-forces Launching a satellite what if we grew up in space ?  Vsauce video Wet washcloth in space lesson notes - Tuesday group Flame in space g-force test pilots. Redbull races Centrifuge training	Kahoot to complete Use a sensible name, so I will know who did it. PIN code for 8A (Tuesday group) 0803392   (updated so it does not expire yet) PIN code for 8C (Friday group) 08909014
45	Acceleration understand the unit for acceleration do simple calculations using the formula a= (change in velocity)/(time taken) Newton's Second Law  F = ma Going through the work done so far and practicing the calculations. Conservation of energy		What is acceleration ? Acceleration due to gravity, g.  Calculating accelerations. Calculating accelerations video Practice acceleration questions Answer sheet Conservation of energy video    Rollercoasters and energy video Tuesday group lesson notes Videos from the Friday lesson F=ma F=ma again!	Study for the open notebook test.  You may think you do not need to study, but if your notebook is to be useful in the test, you need to know what is in it.  Here is a video for tips too, which goes through each point below on the tips page . Your absolute priority this week is to make sure none of your notes are missing.
46	Going through the work done so far for the test		Tuesday group notes	Study for the test. Do not forget your notebook next lesson! Kahoots: The one from the lesson this week 04991689 (with 50 questions) Gravity 07042350 Terminal velocity 06128720 Recording data 01911893 Velocity and speed calculations 07817679 Showing movement on graphs 04518927 Newton's first law 08971074
47	TEST
48	Centre of gravity/mass and pressure	Alll objects have a ‘centre of gravity’ which is essential for understanding balance (equilibrium) When the centre of gravity lies outside the base area, the object falls Stable objects do not fall, unstable objects fall and objects in neutral equilibrium can roll The pressure an object passes on to what is under it depends on the weight of the object and the area of contact: Pressure = force/area Pressure is measured in Pa, pascals or N/m2 newtons per square metre	Lesson notes Tuesday Toe touching fail! Balance board PPT (intro) Centre of mass/gravity What is centre of mass? very short video Stable, unstable and neutral equilibrium video (ball, pencil) Fosbury Flop Ted-Ed video Snow shoes and pressure Other examples of pressure: blood pressure, atmospheric pressure pressure =force/area For the atmosphere, there are approximately 10 000 kg/m2 Windy.tv Examples Safety video: Surviving falling through the ice   (pressure)	This link - you will need your Ilmiö book
49	Traffic safety	The amount of energy a moving object has is given by  ½ mv2    where m is the mass of the object, and v its velocity If the speed of a car doubles, its kinetic energy has quadrupled The distance which a car needs to stop depends on The speed of the car The road conditions The time taken for the driver to react The exchange of energy in a crash can be done more slowly if materials within the crash can compress or stretch; this can then reduce the damage e.g. use of seat belts, airbags	Car crash documentary Stopping distances - Finnish road safety Swedish road safety page - has more explanation Physics of car crashes
50	Autonomous vehicles		Helsinki fleet of robot buses video YLE article Google self-driving car project The truth about self driving cars 30 mins 1 year old the measure of all things about light, heat and electricity
