Kinesiology 2241A/B Lecture Notes - Lecture 9: Angular Velocity, Angular Acceleration, Kinematics
Document Summary
Forces are the genesis of all kinematics. Have looked at it from a linear view position, distance, and displacement: When talking about angular movement (ones on slide 1), we do that all the time. Linear movement is a result of angular movement. In curling, need to open up knee joint and to do this have to open up 2 segments. To get the rock to move in a straight way, use angular movement angular kinematics: Angular movement is a vector quantity with direction. Right hand rule determines what is positive and whats negative. Move hand in direction its moving and stick thumb up- that determines sign of vector. Clockwise rotation is assigned a negative value in all instances. Things that are counter clockwise is a positive value angular displacement: Static with angular displacement- angle b/w line segment and its initial position. Use theta to determine angle absolute and relative body angles:
