Hold ruler between person’s thumb and index finger, lined up with 0cm mark. Drop without warning, and record distance dropped before caught
3
New cards
What is step 2?
Calculate the reaction time using Newton’s equation of motion, so t=squroot 2s/a
where s = distance dropped in metres, and a = 9.8ms-²
4
New cards
What is step 3?
Carry out repeats, but be aware that the person will likely improve over time
5
