Kinesiology 2241A/B Lecture Notes - Lecture 27: Blue Arrow, Ski Jumping, Weightlessness
Document Summary
Drag coefficient: the drag coefficient, cdrag, is dependent on the body positioning of the cyclist, the most upright has the highest drag force. A race position has the smallest drag force, but is far less comfortable. Projection angle: the angle between the velocity vector and the horizontal ground is called the projection angle. Note that the projection angle does not need to be the same as the angle that the object (in this case the javelin) makes with the ground. Projection angle- the direction the center of mass is travelling with respect to horizontal (blue arrow is the velocity), the direction the object actually goes. If negative, travelling downwards till you hit the: the angle between the object orientation and the horizontal ground is called the attitude angle. This angle is usually different from the projection angle. ground. How the object is oriented with respect to the ground.
