Thread: How to measure how fast you bowl?

1. How to measure how fast you bowl?

I recently saw in this forum how you could measure how fast you bowl using a stopwatch and calculator but have forgotten how to do it?

Could someone please tell me how it is done again please?
Thanks.

2. Copied from the Cricket Web coaching section:

Finally, we've got everything sorted out - so how fast do you actually bowl? Naturally, the best thing possible to use would be a radar gun - however they're not generally widely available to clubs and schools - but there is a simple way that needs just a stopwatch and a calculator (or maths geek) to provide approximate results. Start the stopwatch when the ball is released, and then stop it again when either the batsman hits (or misses) it, then divide 45 (or 72) by your answer to get your answer in miles per hour (or kilometres). For example, a delivery timed at 1 second has travelled at about 45mph (72kph). To break the magical 100mph (160kph) barrier, the clock must register at 0.45 seconds. Once you get used to working the timer, you will get surprisingly consistent results. I've found that standing at the back of the net, either directly behind or just to the side, gets the best results.

3. Thanks for the quick reply.

4. im baffled........how does it work......i did it and it came out like 2mph

Maybe you're a slow bowler?

6. do 45/(your time in seconds like 0.64 for example), you've probably done it the other way around.

7. im using the stopwatch on my watch.....so thats why im confused.......what stopwatch do you use?

8. I assume you're supposed to have someone else operating the stopwatch...?

9. No.....im measuring my mate's speed but still aint getting any proper results as i dont get how to do it using my watch

10. I actually bought a radar gun, but found it hard to get an accurate reading. I suggest using a combination of the stopwatch method and a video camera.

im sure thats more accurate once you get used to it, maybe ask a cop for some tips?

It doesn't matter what stopwatch you use - just use something that can record split seconds (milliseconds?). Anyway, get your time, and divide 45 by it - say, it was one second. You would do 45 divided by 1 (45/1) = 45 mph.

I guess that someone that is really bored can make a table for this kind of thing.

Neil's already done it

14. Didn't you ever do physics?

speed=distance/time

But the results will be different from what you see on TV, as they record the speed as the ball is released rather than as it reaches the batsman.

15. This would be measuring the average speed though wouldn't it.
