I realize that an expression for g should be g = a/sin(theta) by looking at the angle that's formed perpendicular to the plane. However, if I just look at angle theta in the bottom left corner, why am I not justified in saying g = sin(theta)*a, since to me it appears that the sine of angle...

Homework Statement Hi, I just had a quick conceptual question. I understand that if I have an object moving down a ramp, it is being accelerated only by gravity. My question is this: We should be able to experimentally calculate g if we measure the acceleration down the ramp. Then we can...
