Exp #1 – A Measurement of the Acceleration due to Gravity
Section 10
Abstract
The goal of this experiment was to measure the acceleration of a lead weight due
to gravity. Essentially we should have got a value of 980 cm/s
2
, which is the
gravitational force felt here on Earth. In our experiment we obtained a value of 966.67
cm/s
2
, which is 1.36% off the actual value.
Theory
It is Newton’s gravitational law that says that everything has a force applied to it
due to gravity no matter where you are in the universe. This changes from place to place
depending on your distance from the center of whatever planet you’re on. The equation
used to find Force is F
g
= M * A. Force of gravity is equal to mass(M) times
acceleration(A). Another equation that is used in this experiment is Velocity = ∆X / ∆T or
X

/ T

.
With this equation we can then get Acceleration which is ∆V / ∆T.
