1.    Determine whether each of the folowing activities requires a static or dynamic analysis: (a) a supermarket chekcer at work, (b) a handstand, (c) a sprint starting position, (d) a hammer throw, (e) the en garde position in fencing, (f) a football line stance, (g) a chip shot in golf, (h) a basketball free throw, (i) word processing, (j) a conformation evaluation of a show horse, and (k) an older adult standing from a seated position.

 A static analysis is made of non-moving bodies, and a dynamic analysis is necessary for bodies in motion.

a) dynamic     b)static     c) static     d) dynamic     e) static     f) static     g) dynamic     h) dynamic     i) dynamic j) static           k) dynamic 

3.    The following statements are from analysis of movement activities.  Indicate which are qualitative and which are
        quantitative.
            a.    The greater the angle of takeoff, the greater the vertical velocity component.
            b.    The angle of takeoff was found to be 23 degrees.
            c.    The style of high jump was more effective for jumper A than for jumper B.
            d.    Jumper A jumped 30 cm higher than jumper B.
            e.    Raising the arms over the head will raise the center of gravity within the body.
            f.    An object swung in an arc and released from its circular path will travel in a new path tangent to the arc at the
                  point of release.

A qualitative analysis excludes measurement of variables, whereas a quantitative analysis describes variables in numerical terms.

a) qualitative     b)quantitative     c)qualitative     d)quantitative     e)qualitative     f)qualitative

5.    Describe three activites in which efficiency should be reduced in favore of effectiveness.

In any activity in which energy must be conserved to complete an event, efficiency is important.  When energy conservation is not necessary, efficiency is reduced in favor of effectiveness.  Examples include any relatively brief effort for speed, accuracy, projectile distance or height, and body maneuvering.

6.    Describe an activity in which force is optimized, but not maximized, for the most effective performance.
 
Free throw in basketball, bunting a baseball, soccer pass, swimming arm pull, dancing steps, tennis drop shot, volleyball serve.
