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?
