RE: Blandom Snuff

I'm halfway done writing a modern fantasy Lovecraftian horror absurdist styled novella.

RE: Blandom Snuff

I'm learning French right now on Duolingo (Level 5 French) and I really want to also learn physics (btw I haven't learned calculus and I am bad with algebra). Is that a good idea?

RE: Blandom Snuff

You'll need some algebra with physics, but not really calculus. Assuming you start with mechanics, you should be fine if you're good at drawing diagrams and visualizing how forces interact.

Oh cool then. I just need to fix up on my Algebra. My interest is classical mechanics and I found this physics website with equations. Now what I'm confused at is the constants.

A constant is just a value. For example, the constant of gravitational acceleration is g, which is equal to 9.81 meters per second squared.

Also sine, cosine, and tangents.
W = F̅Δs cos θ

What the hell? Why is it asking me to find an angle for work?

RE: Blandom Snuff

Work is force times displacement in a certain direction. Remember that cosθ = adjacent / hypotenuse. In this case, the work is the hypotenuse. So multiply both sides by the adjacent, you get adjacent * cosθ = hypotenuse. Then adjacent is just F̅Δs, so Work = Hypotenuse = F̅Δs * cosθ = F̅Δs cosθ

Constants also never change (or at least should not).

RE: Blandom Snuff

Caesar:

It includes cosθ because work can only be from force parallel to the distance. So, if you push a box up a hill by only using a horizontal force it's not only inefficient, but you haven't done a ton of work (force applied * horizontal distance from base of hill to crest of hill).

Hope that helps!

Also, this engineer says physics is awesome, so good on you for learning it!
