Circular Motion

Recommended Posts

I have body moving at a constant speed. If the body turns at a maximum rate of some arbitrary degrees/radians per second, what is the radius of the circle the body makes as it moves? All I know is the speed and turn rate of the body. My physics skills are a little rusty when it comes to some of this stuff. Does anyone know how to calculate the radius?

Well there are 2 pi radians in a circle so the arclength of an arc of x radians is radius*x (hence the only real reason to use radians) . If your arclength is position=velocity*time and angle=angularvelocity*time then
angularvelocity*time *radius = velocity*time
radius = velocity/angular velocity

Thanks for the reply. I had seen a that equation in other places in my search, but I hadn't understood things. It seems like a no brainer now, but Angular Velocity == my radians per second. Thanks again for the help.
