School Science Projects

Okay, so my friend and I were riding in the bed of my buddies truck, and my friend says to me that if you were to jump straight up out of the truck at say 30mph, you would land without falling.

My argument was that you would be also traveling at 30mph or something near there, so when you landed you would fall/roll/etc.

He got so defensive saying you could land and stay up because he says you aren’t moving with the truck. So please someone give me the science behind this to either:

A.) admit defeat
or
B.) blow his mind with a detailed scientific explanation to why he is wrong

thank you

i mean last weeeek i had 15 best and now it is redused to 7 yyyyyyyyyyyyyy???????

I am looking for a person to share fiction, science fiction, poetry etc. back and forth with for criticism etc. I would do the same for you…

can anyone tell me what activity should i perform for my science project?

Ok so my boyfriend goes and works out with his buddies twice a week and they do the exact same thing. Boyfriend is 5′4 and 120lbs and his friend is 6′1 and started at 255 but is down 15lbs already. Not that he wants or needs to lose weight, just curious about the science, why is his friend losing weight and he’s not?
