physics

4. the typical speed of sound in air
6. identical flasks/same amounts of hot water/same starting temperature of the water/same time interval
10. radio/tv
11. what you measure
12. force/cross-sectional area
16. magnet that is always magnetic
17. medical treatments/imaging
18. when something gives off something
22. have magnitude (size) only
23. colour of surface
25. force x distance
30. newtons law force = mass x acceleration
31. seeing/photos
33. have magnitude & direction
35. reached when drag force equals that force in the opposite direction
37. the typical cycling speed
38. forgery/tanning
40. waves that are parallel to the direction of travel
41. 1/frequency
42. newtons law something will stay still or moving at constant speed unless a resultant force acts on it
43. good emitter
47. temperature change
48. how far an object has travelled
49. cooking/mobiles

1. what you change

20. reasonable emitter
21. what you keep the same
24. the area around a magnet where a magnetic object experiences a force
26. the typical car speed
27. poor emitter
28. dependent side on the graph
29. always conserved in a closed system
31. speed in a given direction
32. independent side on the graph
34. medical treatments/imaging
36. magnet that can turn on/off by electricity
39. newtons law every force has another force that is equal in magnitude but opposite in direction
44. when something takes in or soaks up something
45. distance/time
46. heat transfer
