I got alittle confused on something...
say an elevator is moving downward and its speed decreases.
If you are drawing a FBD of a block inside the elevator,
there are only two forces acting on the block, normal force from the elevator floor and weight force. But since elevator is decreasing...
Does anyone know a site that shows how to draw angles using only a ruler and a compass?
60 degree, 35 degree, 45 degree angels ect.
Any explanation on how to do this would be great. I have to show curves to signify that I used the compass and I believe the method involves a point of...
Hi ,
I have drawn a line between two co-ordinates say (x1,y1) and (x2,y2). I have a point called (x3,y3) . From the point (x3,y3) i need to draw a perpendicular line to (x1,y1) and (x2,y2). so that i will be able to find the perpendicular distance . Is there any formula for calculating or...
forces exerted by a magnet
After learning about the right hand rules for a magnet on a wire, my packet asks for me to draw the vector diagram for the force F from a magnetic field B on a moving positive charge with velocity v. What is it looking for? I don't know if B is into or out of the...
Hi,
I'm seeking for a software, witch will alow me to easily draw Feynman diagrams.
I have currently found:
FeynMF: LaTeX package. Not very nice to use, but very good quality diagrams
FeynmanDraw: Very primitive WIN software. Not fine diagrams.
FeynDiagram: C++ source for drawing...

Our physics teacher gave us some chapter review questions from another book and I don't understand exactly what to do. Here is the question:
a) TownA is located 380km[S64oW} of TownB. Draw a displacement vector diagram and a velocity vector diagram to the same scale.
(Our book only shows...
Hey all,
I'm a junior in high school and taking physics. My teacher isn't really one of the best teachers, and we do nothing from a textbook, all done from her drawings/lectures from a whiteboard.
It's safe to say I'm just about completely lost in that class. We have a test coming up...
