Lab 2: Motion under 1 – Dimension: Graphical Analysis: A graph, like a picture, is worth a thousand words. Graphs not only contain numerical information; they also reveal relationships between physical quantities. This lab uses graphs of displacement, velocity, and acceleration versus time to illustrate one-dimensional kinematics
By the end of this lab you will learn:
Describe a straight-line graph in terms of its slope.
Determine average velocity or instantaneous velocity from a graph of position vs. time.
Determine average or instantaneous acceleration from a graph of velocity vs. time.
Derive a graph of velocity vs. time from a graph of position vs. time.
Derive a graph of acceleration vs. time from a graph of velocity vs. time
Materials: Stopwatch, Pencil, Graph paper, Calculator, Eraser, and wonderful yourself!

+Activity 2:
Part I: Find your speed:
Step 1: Mark the floor with a Distance lets say: 300 cm
Step 2: Take a timer app and measure the time (t) in seconds to walk 300 cm, covert the distance to meters.
Step 3: You have Distance from Step 1, Time (t) in seconds from step 2, Find your Velocity (v)
Part II: Find time you will take to walk form Utica train station to MVCC
Step 4: Distance between Utica train Station and MVCC is = 2.6 miles
Step 5: You have Distance = 2.6 miles, and Velocity from step 3, Solve Velocity = Distance / Time for time and find duration of your walk, Convert time from seconds to minutes.

How to write lab reportHow to write lab report
The purpose of the lab report is for you to convey what have you learned form lab exercise. The lab report should be divided in to three different sections.
1) Introduction
2) Observation and Calculation
3) Conlclusions
1) How to write introduction section?
While writing introduction section ask yourself following questions:
What is the objective of the lab? What law or hypothesis are we analyzing? [10 points]
What equipment we are using for lab and how is the lab designed? [10 points]
Please be as specific as possible in your explanation.
2) How to write the Observation and Calculation section?
This section should include image of you lab set up, observation table, graphical analysis and data recorded during in lab activity. The data should be substituted in to equations and variables should be calculated. Full grades will be awarded when all units are written and data is systematically recorded.
Image of your experiment set up [10 points]
Compltely filled data table [10 points]
Equation used to perform lab [ 5 points]
Sample calculation [15 points]
Graph (if any) [10 points each graph]
Units associated with data [10 points]
3) How to write conclusion section?
While writing conclusion section ask yourself following questions
Data Analysis :Do theoretical value and practical value agree with each other? If, No why? If, Yes why? [5 points]
Error Analysis: Do you have any errors in your data? if so what are those error? [5 points]
Critical Thinking: If you achived the results of experiments by altering some part of the experiment share that [Optional +10]
Analytical Thinking: Write a statement combining your experimental data with objective of lab of the lab. [10 points]
