How fast does the CB travel for a range of shots?
Here are some typical values for various shot “speeds” in miles per hour (mph), feet per second (fps), inches per second (ips), centimeters per second (cm/s) and meters per second (m/s):
- soft touch: <1 mph = <1.5 fps = < 18 ips = < 45 cm/s
- slow: 1-2 mph = 1.5-2.9 fps = 18-35 ips = 45-89 cm/s
- medium: 2-4 mph = 2.9-5.9 fps = 0.89-1.9 m/s
- fast: 4-7 mph = 5.9-10.3 fps = 1.9-3.2 m/s
- power shot: 7-10 mph = 10.3-14.7 fps = 3.2-4.5 m/s
- powerful break: 25-30 mph = 37-44 fps = 11-13 m/s
- ridiculously powerful break: 35 mph = 51 fps = 16 m/s
One way to characterize different shot speeds is in terms of “table lengths of travel.” Refer to TP B.6 – Cue ball table lengths of travel for different speeds, accounting for rail rebound and drag losses to see how shot speed and “table lengths of travel” are related.
