Materials:

-­‐1
trolley
that
will
be
accelerated
-­‐1
string
to
connect
the
trolley
and

the
weights
(ca.
2m)
-­‐1
set
of
weights
that
will
accelerate
the
trolley
(up
to
5N)
-­‐1

to
measure
the

D.1
Aim
of
Experiment:

^Trolley

The
aim
of
this
experiment
is
to
test
Sir
Isaac
Newton’s
second
law
of
motion
F=ma
(1).
We
will
be
testing
this
by
accelerating
a
test
trolley
(Trolley’s
weight:
667.29g)
attached
to
a
weight
hanging
off
a
table
over
an
acceleration
meter
(smart
pulley).
The
a.m.
(2)
is
connected
to
a
device
that
measures
and
graphs
any
de/acceleration
that
a
cured.
We
will
plot
the
results
and
determine
our
final
data
by
the
plots

-­‐1
long
testing
plank
where
the
trolley
can
accelerate
on
-­‐1
table,
or
other
type
of
elevation
so
that
the
weight
can
fall
somewhere
-­‐1
paper
and
pencil
/
computer

plotting
results

Method:

D.2
Hypothesis:

m
a

I
think
that
the
higher
the
force
the
faster
the
acceleration.
Since
F=ma
and
a=F/m
and
the
force
is
what
we
change,
we
will
need
a
higher
force
to
increase
the
acceleration.
If
the
equation
a=F/m
is
true
the
acceleration
and
the
force
will
be
directly
proportional
because
there
are
no
exponential
or
fraction
in
the
equation
which
makes
it
directly
proportional.
(The
force
is
the
weight
accelerating
the
trolley).

D.3
Variables:

Independent
variable:
-­‐We
will
be
changing
the
Force.
{Newton’s
(N)}
Dependent
variable:
We
will
be
measuring
the
acceleration
of
the
trolley.
(m/s^2)(3)
Control
variable:
-­‐We
will
keep
the
weight
of
the
trolley
the
same.
(667.29g)
-­‐We
will
keep
the
testing
plank
the
same.
-­‐We
won’t
change
any
properties
of
the
acceleration
meter.
