A
What distinguishes mass from weight? A. Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object. B. Weight is a measure of the amount of matter in an object, while mass is a measure of the force of gravity on the object. C. Mass is a measure of an object's inertial force, and weight is the force exerted by that object on other objects. D. Mass and weight are synonyms and ultimately describe the same principle.

B
Which of the following BEST explains why stability is an important skill for athletes? A. Without good stability, athletes cannot participate in sports. B. Without good stability, athletes are too clumsy to perform well. C. Good stability helps athletes improve their speed. D. Good stability helps athletes deal with their injuries.
B
Which of the following does NOT limit range of motion? A. weak muscles B. age C. disease D. bone structure
B
Why does range of motion need to be measured separately for each joint? A. The average ranges of motion of joints are not known. B. Each joint has a different range of motion. C. Range of motion can change rapidly in a joint. D. none of the above

C
The joints in the fingers are __________. A. pivot joints B. saddle joints C. condyloid joints D. ball-and-socket joints
C
What is BEST to say about a runner who is running at a constant velocity? A. Their acceleration is positive. B. Their acceleration is negative. C. Their acceleration is zero. D. Their acceleration cannot be determined.

Which of the following describes the BEST strategy for increasing a specific joint's range of motion? A. developing a rigorous whole-body exercise program B. avoiding stretching before vigorous exercise C. applying the principles of overload and progression to exercise the joint D. spending two hours swimming daily
C
Which of the following statements about stability is NOT true? A. Skilled athletes have high levels of stability. B. Stability can be learned through practice. C. Stability is genetic and cannot be improved. D. Stability requires an awareness of your center of gravity.
C
Why do women typically tend to have slightly greater stability than men? A. Women are shorter than men, and shorter people are more stable. B. Men have more muscle mass in their lower bodies that makes them stiff and less stable. C. Women have lower centers of gravity, and lower centers of gravity provide more stability. D. The increased muscle mass in their upper bodies makes their centers of gravity difficult to find.

D
Range of motion is the distance an object can travel when separated from another object.
