I need physics help! hahaha.
anyone with any tips on converting computations. i forgot all that stuff.
like velocity=distancextime or something, stuff like that. anything will save my life. my professor does not know how to teach and I dont get my textbook in the mail til like, next week so I need to find some crazy research somehow.
Help this poor student! I wanna cure cancer! :(
No hot chick in the class you can study with?
You were close..........Quote:

Have a good one!:s4:
V2 = V1 + a(t)
V2 is the final velocity V1 the start velocity a is acceleration t is time (more accurately the change in time)
x = V1(t) + 0.5(a(t)2
x is the distance travelled btw the t is squared in this equation
also the biggest physics formula of them all (although it is forces and not kinematics like above)
F=M(A)
F is the total force M is the mass of the object and A is its acceleration
OMG WUT LOL
What??? why cant we just keep things simple?Quote:

Doesn't get much simpler really :)
I learned loads of these formulas at school (2 or 3 years ago) and have neither remembered any or for that matter needed any since leaving Einstein, Newton and Co. have got a lot to answer for LOL

P.S. there is a little brewery in Hertfordshire that makes Newtons cider, bit of a coincidence or what?
Or in the case of hydraulics and pneumatics.............Quote:

Have a good one!:jointsmile:
HAJK,
Psycho4Bud is the resident hydraulics/physics expert around here. Not me. I have had one semester of very basic college physics about 100 years ago, and I'm stilll trying to erase those memories from my mind. Now if you have any questions about human anatomy or physiology, medical microbiology, or medical biochem, that's more up my alley . . . .

but i got some good stuff today after work just now. i got like all these formulas.
like..
d=v/m for density
m=dv for mass
and v=m/d for volume
those are the basic ones i needed for this lab im doing right now. were just measuring volume and density and stuff for these iron and copper rods. everyone wanted me to do their work because im a master of the triple beam scale. ill leave that knowledge of mine to your own imagination ;)
