Name: Experimentally Graphing Uniformly Accelerated Motion Category: Kinematics Date Added: 16 January 2015  09:38 AM Submitter: Flipping Physics Short Description: None Provided We experimentally determine the position, velocity and acceleration as a function of time for a street hockey puck that is sliding and slowing down. Is it uniformly accelerated motion? Content Times: 0:16 Experimental graph of position as a function of time 0:43 Deciding what the graph of velocity as a function of time ideally should be 1:35 Experimental graph of velocity as a function of time 2:11 Deciding what the graph of acceleration as a function of time ideally should be 2:57 Experimental graph of acceleration as a function of time Multilingual?

Name: Understanding Uniformly Accelerated Motion Category: Kinematics Date Added: 09 December 2014  02:05 PM Submitter: Flipping Physics Short Description: None Provided Students sometimes have a difficult time understanding what acceleration in meters per second squared really means. Therefore, I present acceleration as meters per second every second instead. This helps students gain a better conceptual understanding of acceleration. Content Times: 0:12 Acceleration is meters per second every second 1:22 The first demonstration 1:56 Finding the velocity at each second 3:18 Finding the position at each second 4:31 The second demonstration Multilingual?

Name: A FreeFall Problem That You Must Split Into Two Parts Category: Kinematics Date Added: 22 May 2014  04:27 PM Submitter: Flipping Physics Short Description: None Provided This is a complicated freefall problem where you have to identify that the velocity at the top of the path is zero in the ydireciton. Furthermore, you have to look at it from the perspective of the whole event and splitting the problem into two different parts. A classic freefall acceleration example problem. Content Times: 0:45 Reading the problem 1:12 Translating the problem to physics 3:04 Starting with the whole event 4:36 Splitting the problem into two parts 6:06 Solving part 1: Going up 8:17 Finishing the problem 9:05 An alternate solution 9:38 The review View Video

Name: Introduction to FreeFall and the Acceleration due to Gravity Category: Kinematics Date Added: 21 May 2014  03:52 PM Submitter: Flipping Physics Short Description: None Provided In this lesson we extend our knowledge of Uniformly Accelerated Motion to include freely falling objects. We talk about what FreeFall means, how to work with it and how to identify and object in FreeFall. Today I get to introduce so many of my favorites: the medicine ball, the vacuum that you can breathe and, of course, little g. Content Times: 0:22 An Example of An Object in FreeFall 0:54 Textbook definition of a freely falling object 1:11 We have not defined a "Force" so this is how we define FreeFall 2:07 No Air Resistance (The Vacuum that You Can Breathe!) 3:10 What does it mean to be in FreeFall? (The Acceleration due to Gravity) 4:41 The Acceleration due to Gravity  Not on Earth 5:24 g is not constant on Earth. Very close, but not quite 5:56 Common Misconception: Objects moving upward can be freely falling 6:35 FreeFall is Uniformly Accelerated Motion 7:27 What does the negative mean in 9.81 m/s^2? 7:57 Is "g" positive or negative? 9:01 How can "g" be not constant and we can use UAM? 10:03 Does mass effect the acceleration due to gravity? 10:47 The Review View Video

Video Discussion: Graphical UAM Example Problem
Flipping Physics posted a topic in Video Discussions
Name: Graphical UAM Example Problem Category: Kinematics Date Added: 21 May 2014  03:48 PM Submitter: Flipping Physics Short Description: None Provided Again with the graphs? Yes. Absolutely Yes. Graphs are such an important part of any science, especially physics. The more you work with graphs, the more you will understand them. Here we combine graphs and uniformly accelerated motion. Enjoy. Content Times: 0:29 Reading the Problem 1:02 How do we know it is UAM from the graph? 1:26 Two different, equivalent equations for acceleration 2:41 Finding acceleration 3:23 Graphing acceleration vs. time 3:44 The general shape of the position vs. time graph 4:53 Determining specific points on the position vs. time graph 6:06 Graphing position vs. time 6:58 The Review View Video

Name: Toy Car UAM Problem with Two Difference Accelerations Category: Kinematics Date Added: 21 May 2014  03:45 PM Submitter: Flipping Physics Short Description: None Provided In this lesson we continue to use what we have learned about solving Uniformly Accelerated Motion (UAM) problems. This problem is more complicated because it involves two, interconnected parts. Content Times: 0:26 Reading the problem 0:46 Seeing the problem 1:11 Translating from words to physics 1:58 Splitting the problem into two parts 3:13 Fixing the knowns (common mistakes) 4:35 How do we know we can use the UAM equations? 5:19 Drawing a picture to better understand the problem 6:00 Finding the missing known 7:29 What are we finding again? 8:45 The end of part 1 is the start of part 2! 9:29 Beginning to solve the problem 11:19 Solving part ( 13:53 What is wrong with solving the whole thing at once? 16:03 Rapping it up!

Name: Introduction to Uniformly Accelerated Motion with Examples of Objects in UAM Category: Kinematics Date Added: 21 May 2014  03:42 PM Submitter: Flipping Physics Short Description: None Provided This is an introductory lesson about Uniformly Accelerated Motion or UAM. I show examples of 5 different objects experiencing UAM, some are even in slow motion. We also learn my simple way of remembering how to use the UAM equations. Content Times: 0:20 Defining what it means to be in UAM 0:40 5 examples of objects experiencing UAM (some in slow motion) 1:50 Disclaimer for the peanut gallery 2:50 The four UAM equations 3:32 The five UAM variables 4:45 How to work with the UAM equations 5:31 One Happy Physics Student!
