Assignment 02

Assignment 2 introduces the concept of acceleration, and defines acceleration in terms of the rate-of-change definition.  You will also learn to estimate a best-fit line for a set of data.

In Assignment 2 you will begin in the Introductory Problem Set assignment to work with the idea of acceleration (rate at which velocity changes). 

In a lab-related exercise you will learn to construct a scatter graph of data and estimate the slope and intercept of a line of best fit. 

In the text you will continue to work on previously assigned questions and problems from the first chapter. 

In a 'randomized problem' you will learn to reason out the acceleration of an object which starts from rest and accelerates uniformly through a given displacement in a given time interval.

What you should know

At this point you should know:

• The definition of rate of change and its application to velocity, displacement and time interval.
• Graphing of data in a specified format.
• The concept of the slope of a graph and its y intercept.

What you will learn

• Reasoning out from the definitions of velocity and acceleration the initial velocity, final velocity, average velocity, change in velocity, displacement, acceleration, time interval of an object which accelerates uniformly for a specified interval.
• Use of a velocity vs. clock time 'graph trapezoid` to represent uniformly accelerated motion on an interval.
• Estimating the 'best fit' line for a set of data.
• The concept and calculation of volume.

Things you are working on that usually take time and continued effort to develop:

• Reasoning from definitions.
• Use and interpretation of 'graph trapezoids'.
• Use of the line of best fit.
• Volumes.
