Thanks for the video! Really helping me with my physics homework! I had a question where I was trying to figure out the maximum angle a driveway could be above the x-axis before it started to roll down given a coefficient of static friction = 0.94. And I figured it out! I'm so happy rn, AP Physics is actually destroying me.

@AMLennon5 жыл бұрын
I certainly enjoy your videos. I have a question based on this video. If a block is at rest on the incline plane at an angle of 30 degrees, would the maximum frictional force that would allow the block to stay in place be calculated using 30 degrees, OR would we have to find the minimum angle of the incline plane needed for the block to slide before we can determine the maximum frictional force? That is, find that minimum angle and then substitute it in the formula for fs(max) = UsMgcos (minimum angle needed for block to slide)?

So this is way more though out for explaining but I'm still confused. I've been given a measure an object of 400g on a protractor of 20 degrees and an equation of sin/cos = u What's the coefficient of friction if I have no other measures to go off other than just an angle. Am I missing something here?

@Weazelmania2 жыл бұрын
@@FlippingPhysicswell I don't want to say I'm a dunce but just utter confusion over the problem at hand. Physics is the weakest part of my scientific journey and it gives me complete brain fuzz. The materials I was given, I feel, were very half assed, so though I now understand from this that cos/sin is the answer, I still don't "get it" in that I'm looking for numbers that I don't see. All I have is an angle of 20 degrees which at the point the object started to slide down the ramp. So what am I not getting? No matter how many times I go over it it just isn't breaking through my mind barrier. I have no distances to work with. Am I being an idiot?

In the end, we prove that the coefficient of static friction between the book and the incline equals tangent(theta). The point is that you need to _understand_ how to solve for that.
