Introduction to Newton's Law of Gravitation

You don't want to disclose your mass...wow...just wow.

.......u sound simple minded...Its a joke dude...if u watch the rest of his videos u'd understand he has a sense of humor >.>

@philster00700 ....and if you paid any attention...It was better to leave his mass as a variable as it helped prove that g = 9.81 as his mass just cancelled out

thanks alot

thank u sal

o yea and for DaAfterburner, this is not a video for you, this is for people intrested in learning some physics, i can see you are surely ignorant, and lack maturity to have respect for other people's work. i can also see you are clearly not fit to even conceptualize the defination of physics, i pitty you.

you people are two suck up, here is someone trying to teach something and all you ppl do is complain. i wanna see some of you even try to do better. Thanks for the explaination Sal, you cleared up some confusion.

huh? ok... just calm down angry man. we just want to learn some physics
