How to calculate critical speed in circular motion ...
Apr 14, 2012· In one textbook, it says that the critical speed is the minimum speed at which an object can complete the circular motion. It gives the formula: v = square root of (g*r) However, in another textbook it says that the formula is: v = square root of (2*g*r) How can there be two different types of equation for critical speed? Which one is correct?
