Motion: Uniform and Non Uniform
Abstract
The object of this experiment was to study and describe motion, either
uniform or non-uniform, of various items, such as a human, basketball, and cart and
ramp. A motion detector was used to collect the data while

Abstract
In this lab students focused on motion, or kinematics, which is the description of how
objects move. In order to describe motion they focused on distance, velocity, and acceleration,

PHYS 221
Abstract
In this lab, we needed to understand torque and angular acceleration in order to
develop an understanding for the moment of inertia. The moment of inertia is the

Lab Partner: Ben Mighall
Abstract:
The objective of this experiment was to study vector addition by using three methods:
component method, graphical method, and force table. The force table is one of the equipment
Results:
The main objective of this lab was to measure the speed of a projectile when
leaving a spring gun and to predict its landing point when fired from a non-zero
angle elevation. Through the use of meter sticks, a spring gun, carbon paper, ruler,

What are field notes
Observational data refer to the raw materials an
observer collects from observations, interviews,
and materials, such as reports, that others have
created. Data may be recorded in several ways:

Force expressed over a distance is work.
W = F dr
The only part of the force that matters is the part in the direction of motion
