KIN 222 Lecture Notes - Lecture 1: Sagittal Plane, Hypotenuse, Free Body Diagram
Document Summary
Sagittal plane: vector has both direction and magnitude. Scalar is just magnitude or a single quantity such as mass: mostly talking about vectors in this class, coordinate systems. "nose-to-tail -> start-to-finish: define positive and negative direction. ), then axes are independent: the vector you are decomposing is always the hypotenuse, break into two vectors that run parallel to the coordinate system. Linear or translational kinematics -> motion of a point on a plane. Focusing on how a point moves side to side and up and down. Not rotational, yet: practicing displacement to velocity to acceleration and visa versa (key concept, distance vs. displacement, distance is scalar and how far travelled. Class 4: acceleration: measure of the rate of change of velocity with respect to time. Class 5: gait: primary factor that distinguishes a walk from a run. Stride velocity = stride length divided by stride time. A test to identify possible health conditions in an individual (eg. blood pressure)
