  • It doesn’t make a difference what color (red or blue) phone cord you use for input A or B.
  • However, the A cord/photogate should be the top photogate.

  • The timer “remembers” all 3 times when you send the car down the ramp. To retrieve the times, just push the corresponding A & B buttons.
resolution
Resolution
  • The smallest interval that can be measured.
the timer has a resolution of 0001 seconds that s ten thousandth s of a second
The timer has a resolution of (.0001 seconds) That’s ten thousandth’s of a second

accuracy
Accuracy
  • Accuracy: how close a measurement is to the true value.

“IFR”Index Finger Release
  • This will make a big difference on the precision of our data!
  • Good “IFR” technique should give us a precision of + or - .0005 seconds
