Biomechanics Exam Review 1
What is biomechanics and how is it different from the two common meanings of kinesiology? - Answer-
Biomechanics is the study of how living things move using the science of mechanics. In the first half of
the twentieth century this was synonymous with kinesiology, but now kinesiology is the academic
discipline of the study of human movement
Biomechanical knowledge is useful for solving what kinds of problems? - Answer-Biomechanics
knowledge solves human movement problems.
Specially in related to injury prevention and improving fitness
What are the advantages and disadvantages of a qualitative biomechanical
analysis? - Answer-the advantages of qualitative biomechanical analysis is its ease of use and flexibility,
but its weaknesses are related to subjectivity and reliability.
What are the advantages and disadvantages of a qualitative biomechanical analysis? - Answer-
quantitative biomechanical analysis have greater precision and accuracy, but its weaknesses are the high
cost in terms of equipment and time.
What kinds of journals publish biomechanics research? - Answer-A wide variety of journals publish
biomechanics research. These journals include specialized biomechanics, engineering, biology, medicine,
strength and conditioning, and sports-medicine journals.
, What is the difference between knowledge and information? - Answer-Knowledge is contextual, theory-
based, and data-supported ideas that make the best current explanation for reality. Information is
merely access to opinions or data,with no implied degree of accuracy.
The most important difference between information and knowledge is - Answer-Information has a
much higher chance of being incorrect than knowledge.
Why should biomechanical knowledge be integrated with other sport and exercise sciences in solving
human movement problems? - Answer-Biomechanics must be integrated with other kinesiology
sciences because people are not robots that move without regard to environmental factors.
Psychological, physiological, and perceptual issues are all examples of factors that might be more
important than biomechanical factors in some situations.
What are major branches of mechanics, and which are most commonly used in performing
biomechanical analyses of human movement? - Answer-Biomechanics has traditionally focused on rigid
body and fluid mechanics. The majority of early biomechanical studies focused on the kinematics of
movement, but there are still many studies on the causes (kinetics) of movement.
What are the specific foci of kinematic and kinetic analyses, and provide some examples? - Answer-
Kinematics is motion description. In kinematics the motions of objects are usually measured in linear
(meters, feet, etc.) or angular (radians, degrees, etc.) terms. Examples of the kinematics of running could
be the speed of the athlete, the length of the stride, or the angular velocity of hip extension.
Kinetics is concerned with determining the causes of motion. Examples of kinetic variables in running are
the forces between the feet and the ground or the forces of air resistance.
How are vector variables different from scalar variables? - Answer-Scalars only require knowledge of
size and units.
Vector variables require knowledge of size, units, and direction.
How is a scientific principle different from a law? - Answer-Scientific principle is working tool of theory
based of science event. It is also to mean the guiding tool of any science philosophy. Whereas law is
ultimate governing law proved through so many scientific experiment. Although the law is universal it
works in specific condition.
