Name: Force vs. Time on a Dynamics Cart Category: Dynamics Date Added: 03 December 2014 - 10:59 AM Submitter: Flipping Physics Short Description: None Provided When the forces in a free body diagram don’t change students often think that Newton’s Second Law will yield the same results. This demonstration shows that is not true. This is a step-by-step analysis of tension force as a function of time for a dynamics cart in motion on a horizontal track. Content Times: 0:13 Reviewing known information 0:47 The three parts in this demonstration 1:22 Drawing the two free body diagrams 2:27 Understanding the free body diagrams 3:12 Identifying the String Direction 4:08 Finding the Tension Force during Part #1 6:06 Theoretical vs. Experimental Tension Force during Part #1 6:28 Finding the Tension Force during Part #2 7:52 Theoretical vs. Experimental Tension Force during Part #2 8:13 Finding the Maximum Acceleration during Part #3 9:37 Instantaneous vs. Average 10:21 All the graphs sequentially Multilingual?

Name: Graphing the Drop of a Ball from 2.0 Meters - An Introductory Free-Fall Acceleration Problem Category: Kinematics Date Added: 22 May 2014 - 04:22 PM Submitter: Flipping Physics Short Description: None Provided This video continues a problem we already solved involving dropping a ball from 2.0 meters. Now we determine how to draw the position, velocity and acceleration as functions of time graphs. Content Times: 0:17 Reviewing the previous lesson 1:00 Acceleration as a function of time 1:31 Velocity as a function of time 2:39 Position as a function of time 3:56 The Review View Video

Name: Walking Position, Velocity and Acceleration as a Function of Time Graphs Category: Kinematics Date Added: 21 May 2014 - 08:56 AM Submitter: Flipping Physics Short Description: None Provided This lesson builds on what we learned about position as a function of time graphs. We start with velocity as a function of time graphs, determine what the motion would look like and then draw position and acceleration as a function of time graphs. We use the concepts of slope and tangent line to help us build the graphs. Content Times: 0:35 What is the slope of a velocity vs. time graph? 2:30 Walking the 1st velocity vs. time example 4:17 Explaining what a constant slope is 7:11 Drawing position vs. time for the 1st example 9:08 The Magic Tangent Line Finder! (defining tangent line) 11:18 A look forward to Calculus 12:51 Drawing acceleration vs. time for the 1st example 14:35 Walking the 2nd velocity vs. time example 15:47 Drawing position vs. time for the 2nd example 17:19 Drawing acceleration vs. time for the 2nd example 18:17 Walking the 3rd velocity vs. time example 20:41 Drawing position and acceleration vs. time for the 3rd example 22:55 Ideal vs. real data View Video

Name: Understanding and Walking Position as a function of Time Graphs Category: Kinematics Date Added: 21 May 2014 - 08:48 AM Submitter: Flipping Physics Short Description: None Provided In this lesson we derive that the slope of a position versus time graph is velocity. We also walk through several position as a function of time graphs to understand what they mean. Content Times: 0:34 Position as a function of Time 1:04 Defining Slope 3:04 The Slope of a Position as a function of Time Graph is Velocity 3:43 Defining Position Locations on the Graph 4:37 1st Graph 6:25 2nd Graph 7:25 3rd Graph 9:18 4th Graph View Video
