![]() ![]() If the particle is moving, the variables x, y, and z change as time goes on. We generally use the coordinates x, y, and z to locate a particle at point P(x, y, z) in three dimensions. In this case, the easiest method is to use. To describe motion in two and three dimensions, we must first establish a coordinate system and a convention for the axes. Projectile Motion (General) xx0+v0xt+12axt2, yy0+v0yt+12ayt2 vxv0x+at, vyv0y+at v2xv20x+2a(xx0), v2yv20y+2a(yy0) (xx0)12(vx+x0x). As in many physics problems, there is more than one way to solve for the time to the highest point. continue in a straight line at constant speed, if it was moving and no net force acts on it. Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. [continue at rest, if it was at rest and no net force acts on it. ![]() Choose all that are correct : gradually come to a stop, if it was moving and no net force acts on it. Solving projectile problems v vxo i + vyo j v(cos() i + sin() j) If we neglect air resistance, the velocity does not change while the projectile is. Question 10 (2 points) According to Newton's First Law of Motion (the Law of Inertia), an object will. Choose only one answer: True False I didn't read the slides carefully or watch the videos so I have no clue, but I'm honest and now I will review the answers to this quiz and make sure I read as many of the slides as I can before class. The change in Time is the same in both directions, since time has no components because time is a scalar, not a vector. Time) Worksheet: Graphs of Motion II ( solutions) Assignment: Kinematics Video Analysis due next class (print and bring to class) Lab: Acceleration due to Gravity Lab complete Introduction pre-lab questions for next class. displacement, velocity and acceleration in the y-direction). (Thu) Notes: Graphs of Motion (Velocity vs. displacement, velocity and acceleration in the x- direction) and one set is for the y-components of the kinematics variables (ie. In projectile motion problems, we use two sets of kinematics equations: one set is for the x- components of the kinematics variables (ie.
