would someone like to write up my lab report for me?

im having difficulty with it..i dont know what to write.

 

the experiment was with ticker tape and we were suppose to find the speed and acceleration and velocity of it. so basically we attached the ticker tape to the car, rolled it down the ramp and measured the dots that came from the carbon paper used by the ticker tape apparatus. and i dont know what to write for the hypothesis and all that stuff because i am a moron and my brainium just recovered from a recent meltdown.

sooo...help??

just tell sir teacher that your brain doesnt compute and your heart is telling you this wouldn't be required in this big wide world anyway :stunned:

 

sorry can't help :( :)

aaahhhhh!

but...im gunna fail and let down my group. thats not fun

speed...acceleration....velocity??

 

no term as 'speed' in physics, i think. it's just acceleration and velocity.

 

F = m*a (force = mass * acceleration).... so, a = F/m. you've to know F and m to get a. F in this case would be weight of the car.

weight, w = m*g = F

g = 9.8 m/s^2 (gravity constant)

m = mass of the car that you must have measured in class/lab (in grams or kilograms or pounds...)

h = height of the ramp (the vertical height)...make a right triangle, etc etc...

 

 

so now you got F and you got already have mass, m. so now go get acceleration, a....

 

now for velocity....since the ramp was too short for there to be a big change in velocity...you can just use average velocity and make life easy for you...

 

avg velo = change in distance/ change in time.

 

I'm sure you knew the distance the car travelled, and you would have had a stop-watch to get the time for the run.

 

Plug and chug!

Sure I'll write it!

wait, whats ticker tape,.... and carbon paper.....

 

on second thought, mybe i shouldn't. but I have an idea! why don't you write it! :D

what all sections are you supposed to have?

 

hypothesis: the distance between each dot is the same if there is no change in velocity.

my bad....speed IS a scientific term....it's a scalar....velocity is a vector. the whole world doesn't give a damn about scalars, really, in the big scheme to things...so you tend to forget about them once you're out of school! lmao

i hate physics...aahhhh!!!!!!! science+math=brainium no werky.

 

ack ack..well, im just going to do it...trying to bullshit it as much as possible.

what?????????

 

I went thru all that trouble and you're not even saying anything???

 

so you didn't need any help afterall? :stunned:

 

:dozey:

I dont know what you're talking about..and...i dont even know what im doing!

Constant acceleration should not be confused with constant velocity. An object with a constant velocity is always traveling at the same speed. An object with constant acceleration is moving faster and faster as time goes by but it increasing in velocity at the same rate over time. Imagine a car with a leaky transmission. Imagine this leak is constant so that the car drops one drop of oil every second. Now imagine this leak of oil being a constant that never changes. If the car had a constant velocity the drips would appear on the pavement below to be evenly spaced. If on the other hand, the car had a constant acceleration the drips would appear to be farther and farther apart as time elapsed. In this activity we will replace the dripping oil leak with a device called a ticker tape timer. A ticker tape timer places dots on a long strip of paper as it is being pulled through the device by being attached to a moving cart. The ticker tape timer places a dot on the paper every 1/60th of a second. This means that 60 spaces between the dots on the paper represent one second. The effect is the same as the leaky oil example, because the spacing of the dots on the tape are timed and therefore are dependent only on the acceleration or velocity of the paper being pulled through it.

 

A useful way to describe an object’s motion is to graph it. Consider a car or cart moving across a table being pulled by a mass hanging over the table edge. The mass may be hooked to the cart using a string and a pulley. Releasing the mass to fall will pull the cart across the table. Assume the object starts from rest and move across the table. If this motion across the table was recorded on a ticker tape, what types of information could be derived from studying this tape? This prompt will ask you to do just that.

 

 

 

"what more do you need??" I gotta get out of the office soon...so if you're just gonna be of no use, i might as well give up and go home....

 

i gave you all the equations to calculate what you need...that's the hardest part for you. the narrative is easy...just start writing things up!

yes...ok..but i gotta write a lab report on the experiment my group did..and im cornfused!

well...what do you need to write in the lab report? do you even know that much?! i gave you the hypothesis already.

oook, well then...blaahh.

what?????????

 

I went thru all that trouble and you're not even saying anything???

 

so you didn't need any help afterall? :stunned:

 

:dozey:

 

lol I couldn't help cos I'm lazy :P

ummmm....here's some advice: don't go into engineering or science when you go to college! :lol: :lol:

 

the secret of getting thru it all is: persistence.

most engineers and scientists are dumbasses like myself....but most of them don't give up that easily..so eventually, they get thru what needs to be done!

im too lazy..bad habit

Busybeeburns, you're into physics/engineering? give this girl some help...

and then lets kick her butt for procrastinating and not doing her home work! :P

don't do any form of mathematics whatsoever :stunned:

im not procrastinating! im doing it now!! and it was assigned today! so im not procrastinating...though, normally i do. so this is a change.

clocks...whatever your name is....i also gave you some part of the 'experimental procedure'...the highlighted text above....

 

so now all you need is some graphs, analysis of graphs (2 lines for high school level! lol), and some conclusion. conclusion can basically give the to-the-point answers to questions: velocity is: x m/s; acc = x m/s2; etc. and then, it can say something like "After conducting the experiment and analyzing the data, we found that our hypothesis is supported by the experimental evidence"....or some such gibberish! :lol:

oh! i thought you were hitting on some deadline and so you were needing help to finish it.

 

well...good luck with it. hope i was of any help to you (doesn't look like it!)

alright.

 

 

 

i dont get it?

you don't get what??

i dont get why i have to write this stupid thing.
