Name: Introductory Kinetic Friction on an Incline Problem Category: Dynamics Date Added: 2016-06-16 Submitter: Flipping Physics You place a book on a 14° incline and then let go of the book. If the book takes 2.05 seconds to travel 0.78 meters, what is the coefficient of kinetic friction between the book and the incline? Want Lecture Notes? This is an AP Physics 1 Topic. Content Times: 0:01 The example 0:13 Listing the known values 1:09 Drawing the free body diagram 1:58 Net force in the perpendicular direction 2:34 Net force in the parallel direction 4:03 Solving for acceleration 5:07 Solving for Mu 5:40 We made a mistake Multilingual?

Name: Relative Motion Problem: Solving for the angle of the moving object Category: Kinematics Date Added: 07 October 2014 - 03:02 PM Submitter: Flipping Physics Short Description: None Provided It is not obvious in all relative motion problems how to draw the vector diagrams. Sometimes the velocity of the object with respect to the Earth is not the hypotenuse of the velocity vector addition triangle. Here we address how to handle a problem like that. Content Times: 0:15 Reading the problem 0:40 Translating the problem 1:52 Visualizing the problem 2:17 Drawing the vector diagram 3:33 Rearranging the vector equation 4:40 Redrawing the vector diagram 5:30 The Earth subscript drops out of the equation 5:51 Solving part (a): solving for theta 6:40 Solving part (b ): solving for the speed of the car relative to the Earth 7:48 Understanding the answer to part (b ) Want View Video

Name: Nerd-A-Pult - Measuring Initial Velocity Category: Kinematics Date Added: 27 May 2014 - 09:29 PM Submitter: Flipping Physics Short Description: None Provided We need to know the initial velocity of a projectile leaving the Nerd-A-Pult. That means we need the initial speed and the initial angle. This video shows exactly how I measured both. Content Times: 0:30 Taking measurements to determine the launch angle 1:20 Finding a triangle 2:02 Defining the angles 3:35 Determining the launch angle 4:38 Using the frame rate to find the change in time 5:08 Measuring the distance travelled during the first frame 6:12 Why initial speed and not initial velocity? 6:39 Determining the average launch speed View Video
