PPT-One Dimensional Motion Acceleration in the Y Direction Notes

Steps To Solve problems with a V 0y Draw a picture Split the problem in 2 parts where the object stops and starts to fall back down Label all that we know and what we want to know Figure out which K equation to use Use Parabolic graph to help simplify situation. Measures How Fast . Velocity . Changes. Motion and Forces Unit Chapter 1 Section . 3. 1. Speed and Acceleration Can Change with Time. Acceleration. 1. Speed and Acceleration Can Change with Time (answers). The pitcher throws. The ball speeds toward the batter. Off the bat it goes. It’s going, going, gone! A home run!. Before landing, the ball went through several changes in motion. It sped up in the pitcher’s hand, and lost speed as it traveled toward the batter. The ball stopped when it hit the bat, changed direction, sped up again, and eventually slowed down. Most examples of motion involve similar changes. In fact, rarely does any object’s motion stay the same for very long.. Bpid0LBTqWg. . Unit 7 . Matter in Motion. Objective unit 7.

Read Chapter 2. HW 2.A : pp. 57-59: 8,9,12,13,16,17,20,26,34,35,38,39.. HW 2.B: pp. 60-61: 46,47,48,50,52, 58,59,61. ,70,71,72-75,80.. Learning Objectives for Chapter 2. Students will understand the general relationships among position, velocity, and acceleration for the motion of a particle along a straight line so that given a graph of one of the kinematics quantities, position, velocity, or acceleration, as a function of time, they can:. Motion in Two Dimensions. Using + or – signs is not always sufficient to fully describe motion in more than one dimension. Vectors can be used to more fully describe motion. Still interested in displacement, velocity, and acceleration.
