Rotating Sky Lab Report
The lab section concentrated on applying the horizon system coordinates, predicting three
declination ranges at certain latitude, and visualizing star trails. The application used during the
lab was Rotating Sky Explorer. The main
MOTION OF THE SUN
The lab of this week mainly aimed at understanding the daily and seasonal motion of the
Sun. The first section focused on differentiating the sidereal day and the solar/synodic day (the
normal day measured by 24 hours). Th

1. Your friends are riding in a van with a large glass window so that you can see inside. The van is
traveling at a constant velocity and you are standing on the sidewalk. When the van passes yo
The Expanding Universe Lab
Introduction: The origin of the universe remains one of the greatest questions in
science. The "big bang" theory places the origin between 10 and 20 billion years
ago, when the universe began in a hot dense state; according to t

PHYSICS 130 LAB: Intro to Motion II - Changing Motion
Overview: In this lab you will use a computer with a rotary motion probe connected to a cart on a track (aka
the apparatus) so as to learn more about constantly accelerated motion in
I. Introduction To Force Diagrams
In front of you or distributed around the room you have a heavy and a light object. For each object
follow the instructions underneath:
A. Pick up (this gives you a sense of it's weight)

Draw free body diagrams for each lettered object:
3. Neither A or B is moving.
4. A is moving to the right. B is falling and speeding up.
1. A pop gun launches a ball along a frictionless barrel.
Newtons laws of motions are three physical laws that law out the basic foundations of
mechanics. They explain the correlation between an object and the force that acts upon it.
Velocity is the rate of change of a position of an object. It is
