completely forgot how to do the force of friction problems

[wooophysics-blog]

i know :(

chrisphysics:

no class, and we still have hw? =(

Vocab

1. TIme interval - the difference between 2 times

2. Displacement - a change in position having both magnitude and direction equal to the final position minus the initial position

3. position-time graph - a graph that can be used to determine an objects velocity and position as well...

Chapter 1 Definitions and Formulas Group D

Words:

independent variable- factor that is changed during an experiment

dependent variable- factor that depends on the independent variable in an experiment

line of best fit- line that best passes through or near the graphed data

linear relationship- relationship between two variables whose graphed data points lie on the same line

Formulas:

quadratic relationship- y=ax^2+bx+c

inverse relationship- y=a/x

Got our tests back and did alright. We also started to go over thermal energy which doesn't seem too hard to understand so far

[wooophysics-blog]

Yeah i hope it's not too bad friday

jfitzpatrickphysics:

Alright day for a first day back from break. Nothing too difficult or unusual. Hopefully the open-everything test friday isn’t too difficult. Don’t think it should be.

Break's over :(

I dont wanna go back to school tomorrow! i barely remember anything that we did the week before break

Lab day

Snow related to physics

[wooophysics-blog]

You basically just used the words we used in physics in the last two weeks to make a sentence lol

nickcongionti:

I think that if i had a railgun, it would generate enough force and do enough work to get rid of the mountain of snow in my driveway

Test

We took a test today on energy and i hope i did good on it

chrisphysics:

Lab! So yesterday we did a lab on how machines can give you mechanical advantage. My group obviously did something horribly wrong, as we got huge percentiles for efficiency, but I guess as long as we mention that we did something wrong in the report, we’ll be fine.

And yes, to answer your questions, I AM aware that the picture is sideways.

The picture is sideways.

haha great caption

ionaphysics:

Nice !

chrisphysics:

Nolan almost got hit in the face today to demonstrate how energy is conserved within a system. Thanks Nolan.

[wooophysics-blog]

Another exciting day in physics!

Today we went over the homework about energy, then we went over the conservation of energy and Mr. Love showed us how it is conserved by using a bowling ball and Nolan

learnin bout energy

Lab

Almost fell up the stairs today. I thought the lab was interesting but im saving the write up for this weekend
