I conducted an experiment, investigating how density affect a projectile with the presence of air resistance. (The object is launched horizontally from a height of 92cm)
Before the experiment, I researched and asked opinions from other people, all of which gave the same view---> greater density=greater distance. And this was the base of my hypothesis....
But the experiment turned out to be the exact opposite of my hypothesis. My results indicate that less density=higher distance. My average results are as follows:
(Objects have the same shape - 60cm^3 block)
1)Wood (density=0.467) - distance = 190cm
2)Wax (0.917) - 125cm
3)Aluminium (2.683) - 58cm
4)Iron (7.817) - 25cm
WHY is it like this? What's wrong? What seems to be the problem?
PLEASE help if you can... and try and explain cearly (my knowledge in physics is only sixth form level)
OH please i beg for your help and opinion..I'm mentally blocked right now, out of ideas... AND in need of some HELP
