Aims :
To calculate the value or the accevation

due to
gravity , I

This is done
by measuring the fire

it takes for the ball to fall a certain

distance ad then SurAt
using to
find the

acceleration

variables :

independent variable-height ,
h

dependent variable -> time , t

control variables -> same steel ball

bearing , electromagnet and distance
Equipment :
behuter light gates
->
steel ball bearing ad
electromagnet
-> I light gates

-> timer
Analysing results :

-> +i at'
use s : ut
reararged to
-> refort stand and clamps
E = zu +
at
-> cushion to break the fall of the ball being
->
put inte the form

mx+c= =

where is ehlt a is t gradient is m

g
y , ,

method :

and the y intercept is ze
experiment
with

1 Set the scow 10cm
up h =
.
as
->
plot a
graph of ch/t against t
2 . tur n the electroraquet a ad attach the ball
->
daw a line or best fit
bearing the gradient
->

calculate :

I
3 . t r n the ragnet of and the ball should drop
->

assess the uncertainties in had I ad the

through the first light gate starting the time
therefore g
4 . the timer will
siop as it
passes through the

second
light gate
Evaluation :
S . record time ,
t for that value of had repeat
It is easy to
compart the result wish the
2 more times
ac tival value o 9 81 .

6 ,
repeat for multiple values o n
render errors :
7 the table
plot results in a

->
uncertainty in measuring h

->
parallax er ror from reading h

sayety !
-> not down
the ball may fall acurately
->
the electromagnes has a current

-
don't
the light gate
get it wet
-> rendan errors are reduced by repeating
-

only switch magnet on when needed

->
the experiment ad finding multiple
a cushion or mat is needed to catch the

values of t .

bal bearing
iclor shad be attached with G
-> must a
damp

so it is stable
