Gravity timer Python code for all

#code to measure acceleration due to gravity by dropping a ball from head Can be done on phones too

import time

n=3

S=5.5*.3

for i in range(10):

a=input() #Press just before dropping after putting ball near head

start=time.time()

b=input() #Press random key just after it hits ground

stop=time.time()

falltime=stop-start

g= 2*S/falltime**2

print('h=5.5 ft Time = ',round(falltime,2),' s ' ,round(g,2), ' m/s^2')

'''

Can make apps, excel sheets etc

old Time = 0.3962876796722412 s g= 21.01322925251021

h=5.5 ft Time = 0.47 s 15.14 m/s^2 tennis ball

h=5.5 ft Time = 0.47 s 14.96 m/s^2 football

Next improvement is to add data analysis on 10 drops.

Will upload in Github as Gravitytimer.py hope to get 1 million follows

There are amazing projects like LIGO
