Hi! Before I begin, thanks for reading this question and even bigger thanks if you answer! I'm in the middle of a Physics Investigation and one of the minor things that I need to include are the properties of a few different materials. So far I've been ok at doing this but have become stuck at cling film and sand paper (!) can you help please? I need to discuss their surfaces and how easily air would pass over them. Thanks again!

Sandpaper rough course harsh abrasive different guages of courseness, Air would not have a problem passing over them however could take longer to travel over sandpaper,
cling film smooth in comparison. and air would travel unhindered.

Well I would think that air would pass easier over cling film than sandpaper due to the texture of the sandpaper surface but cling film is quite static so I'm not sure if that could affect it...doubt it though.

clingfilm would have air pass over easily as it is smooth and sandpaper would provide more resistance.
