Name: (Part 1 of 2) An Introductory Projectile Motion Problem with an Initial Horizontal Velocity Category: Kinematics Date Added: 22 May 2014 - 04:49 PM Submitter: Flipping Physics Short Description: None Provided Can you drop a ball from a moving vehicle and get it to land in a bucket? You can using Physics! In this video we solve an introductory projectile motion problem involving an initial horizontal velocity and predict how far in front of the bucket to drop the ball. Content Times: 0:17 Reading the problem. 0:41 Visualizing the problem. 1:18 Translating the problem. 2:31 Converting from miles per hour to meters per second. 3:10 Two common mistakes about projectile motion givens. 4:29 Beginning to solve the problem. 5:13 Solving for the change in time in the y-direction. 6:22 Solving for the displacement in the x-direction. 7:29 Video proof that it works. 8:14 Air resistance? 9:09 In our next lesson...

Name: The Drop and Upward Throw of a Ball are Very Similar Category: Kinematics Date Added: 22 May 2014 - 04:25 PM Submitter: Flipping Physics Short Description: None Provided Previously we determined the motion graphs for dropping a ball from 2.0 meters and throwing a ball up to 2.0 meters and catching it again. In this video I show that the reverse of the drop coupled with the drop itself is the same thing as throwing the ball upward. Make sense? Okay, watch the video. Content Times: 0:13 Reviewing the previous graphs 0:25 The drop is the same as the 2nd half of the drop 0:48 Dropping the medicine ball in reverse 1:16 Bobby reviews 1:35 Links to Previous and Next Videos View Video

Name: Analyzing the Apollo 15 Feather and Hammer Drop - A Basic, Introductory Free-Fall Problem Category: Kinematics Date Added: 21 May 2014 - 03:54 PM Submitter: Flipping Physics Short Description: None Provided Apollo 15 Video Courtesy of NASA: The 1971 Feather and Hammer Drop Experiment performed by Astronaut David Scott. We analyze the experiment to determine the height from which the feather and hammer were dropped. It is a great, basic, introductory free-fall problem. Content Times: 0:19 Why the experiment was done. 0:32 Let's enjoy the video 1:27 Beginning to analyze the video 2:23 Using the Frame Rate 3:00 Counting the frames 3:50 Solving for the initial height 4:51 The answer to how high the feather and hammer were dropped 5:31 The Review View Video
