v=2πrT In Physics, Uniform Circular Motion is used to describe the motion of an object traveling at a constant speed in a circle. The speed of the object, also called tangential velocity, can be calculated using the formula above. Here, r represents the radius of the circle, T the time it takes for the object to make one complete revolution, called a period. Determine which of the following formulae could be used to find the length of one period if one knows the tangential velocity and the radius of the circle?
T=v2πr
T=2πrv
T=2πrv
T=12πrv
A
T=v2πr
B
T=2πrv
C
T=2πrv
D
T=12πrv
