Lab Report 2: The acceleration due to gravity
Abstract:
This experiment is designed to find the acceleration due to gravity on the earth using a weight,
wax paper, a standee and a voltage box. We will be computing the acceleration of the weight by
dividing the distance travelled in .0167s (6 dots from the initial dot) by .0167s to find the
velocity and then to find the acceleration due to gravity we need to plot the velocity versus time
graph which we found to be 9.79 ±.07920 m/s². in order to do this we needed to plot the points
and add a best fit line to find the acceleration.
Question
1)
Displacement, (x), is the area under the graph of velocity versus time which is the total
distance the objected travelled. Average velocity,
(
=
=


vinst
∆x∆t
xf xitf ti
)
, is the
change in distance over change in time. Instantaneous velocity,
(
=
)
vavg
dxdt
, is the
derivative of data over derivative of time. Acceleration,

)
a
∆v∆t
dvdt
∆x∆t ∆t
, is
the slope of the velocity and time graph.
