How To Calculate Your Reaction Times With A Ruler - h2g2

WebApr 29, 2008 · The formula we need is: reaction time = square root (distance fallen in centimetres / 490) We know that the ruler fell 14cm before it was caught. So we divide 14 by 490 and take the square root. This gives a result of 0.169. The reaction time was 0.169 seconds, or 169 thousandths of a second. WebBiology: Reaction Time Lab Introduction: A meter stick can be held perpendicular to the floor, dropped, and a student can catch it to determine how far it falls before the student reacts. The slower the reaction on the part of the student, the farther the meter stick will fall. The student can convert distance into times and measure reaction time. fluids in lungs and hearts

"WebFeb 20, 2024 · Since elapsed time is Δt = tf − t0, taking t0 = 0 means that Δt = tf, the final time on the stopwatch. When initial time is taken to be zero, we use the subscript 0 to denote initial values of position and velocity. That is, x0 is the initial position and v0 is the initial velocity. We put no subscripts on the final values. " - Reaction time equation physics
