Fn = m a cosΘ Fn = mass x acceleration (the accel. of the object, not of gravity) Are either of these right? I'm just not getting it! The diagram isn't helping me as much as I thought it would.

To find Fn, what equation do I use? I can't seem to figure it out.

1. A 3 kg block slides down a 30 degree incllined plane with constant acceleration of 0.5 m/s2. The block starts from rest at the top. The length of the incline is 2m. a) What is the velocity of the block at the bottom? b) What is the magnitude of the normal force? c) What is the coefficient...

Can somebody explain how standing waves are formed (both open end and closed end) and what exactly they are?

Thanks for the help.

Can somebody please help me understand conservative and non-conservative forces? My teacher didn't really spend too much time teaching it. Can somebody explain it in the simplest terms possible?

Yeah, that helps me understand it more.

I'm confused about conservative and non-conservative forces from a note I took in class. This is basically the note: Conservative (force of gravity, effort force) -is the force that does work on an object -amount of work is independant of the path taken -it takes the same amount of work...
