Objectives:
The objective of this experiment was to investigate what variables influence the period of a simple pendulum. Theory:
A simple pendulum may be described ideally as a point mass suspended by a massless string from some
point about which it is allowed to swing back and forth in a place. A simple pendulum can be approximated by a
small metal sphere that has a small radius and a large mass when compared relatively to the length and mass of the
light string from which it is suspended. If a pendulum is set in motion so that it swings back and forth, its motion
will be periodic. When we speak of the motion of the simple pendulum, we refer to the oscillations it performs,
when the bob is taken to a height (the string remaining taut) and released.
Materials and Methods:
A mass was placed on a string and attached to a ring stand. A protractor was used to measure the angle at which the string was initially held, and it was then released. A stopwatch was used to record the time of 10 oscillations, and thus the period was calculated. For the second experiment, different masses were attached to the string, and the same method was used to calculate the period. Finally, the length was adjusted and the period was calculated in a similar manner. Data Tables

Homework 3
In a media spectacle, Elon Musk successfully used a Falcon Heavy rocket to launch his personal Tesla
Roadster into orbit around the Sun. (The picture below is real, not CGI!)
Like other objects in orbit around the Sun, the Roadster obeys Kepler's Laws. Given that the Roadster orbits
with an aphelion distance of 1.67 AU and a perihelion distance of 0.99 AU, what is the orbital period (that
is, the time that it takes to make one orbit around the Sun) in years of the Roadster?
