Name: Don't Drop Your Camera 5.0 Seconds After Liftoff Category: Kinematics Date Added: 22 May 2014 - 04:31 PM Submitter: Flipping Physics Short Description: None Provided An advanced free-fall acceleration problem involving 2 parts and 2 objects. Problem: You are wearing your rocket pack (total mass = 75 kg) that accelerates you upward at a constant 10.5 m/s^2. While preparing to take pictures of the beautiful view, you drop your camera 5.0 seconds after liftoff. 5.0 seconds after you drop the camera, (a) what is the camera's velocity and ( how far are you from the camera? Content Times: 0:17 Reading the problem 1:26 Understanding the problem using a picture 2:10 Listing every known variable 3:22 Which part do we start solving first? 3:47 What do we solve for in part 1? 4:46 That's a lot of subscripts, why? 5:24 Starting to solve the problem. Finding the final velocity for part 1. 6:32 Solving for the final velocity for part 2 for the camera 7:46 Why is the final velocity for part 2 for the camera positive? 9:10 Finding the displacement for part 2 for the camera 9:55 Finding the displacement for part 2 for you 10:42 Finding the distance between you and the camera at the very end 11:27 The Review Want Lecture Notes?

Name: A Free-Fall 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 free-fall problem where you have to identify that the velocity at the top of the path is zero in the y-direciton. Furthermore, you have to look at it from the perspective of the whole event and splitting the problem into two different parts. A classic free-fall 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: Throwing a Ball up to 2.0 Meters & Proving the Velocity at the Top is Zero Category: Kinematics Date Added: 22 May 2014 - 04:23 PM Submitter: Flipping Physics Short Description: None Provided In the previous lesson we dropped a ball from 2.0 meters above the ground and now we throw one up to a height of 2.0 meters. We do this in order to understand the similarities between the two events. Oh, and of course we draw some graphs. This is an Introductory Free-Fall Acceleration Problem Content Times: 0:18 Reviewing the previous lesson 0:34 Reading the new problem 1:26 Acceleration vs. time 1:59 Velocity vs. time 2:49 Position vs. time 4:16 The Velocity at the top is ZERO! 5:50 Comparing throwing the ball to dropping the ball 6:56 Finding the total change in time 7:44 Finding the velocity initial 9:47 The Review View Video

Name: Introduction to Free-Fall 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 Free-Fall means, how to work with it and how to identify and object in Free-Fall. 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 Free-Fall 0:54 Textbook definition of a freely falling object 1:11 We have not defined a "Force" so this is how we define Free-Fall 2:07 No Air Resistance (The Vacuum that You Can Breathe!) 3:10 What does it mean to be in Free-Fall? (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 Free-Fall 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
