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: Introduction to Relative Motion using a Quadcopter Drone (UAV) Category: Kinematics Date Added: 23 September 2014 - 03:21 PM Submitter: Flipping Physics Short Description: None Provided Two vehicles driven at different speeds parallel to one another is a great one dimensional way to introduce relative motion. When viewed from above using a quadcopter drone, it is even better! Thanks Aaron Fown of View Video
