I am very confused with a particular aspect of part of my physics curriculum.
Let's say there is an object swinging on a rope swinging in a circular motion. The mass of the object, length of rope, and angle of rope relative to y-axis are known.
How does one derive the tension of the rope...
Ok, I see my errors in judgement now. After a little research I found out the lift comes from air pressure, not friction with the air. I think it's the Bernouli Affect that says when air is moving faster there is lower pressure. Since the air is freely flowing over the side spinning away from...
I had considered spin but I can't think of any solutions for that that aren't overly complicated. The problem is that it needs to spin forward, backwards is easy because it does it naturally, but forwards requires some trickyness.
I'm building a catapult meant to fire a plastic ball as far as possible with the following items: 36 popsicle sticks, glue, 6 rubber bands, 4 clothes pins, a small stryofoam cup, and 4 feet of string. The ball has a radius of just under an inch, and it is very light. I am not meant to modify...
