Question 1

Clinical and sports bio mechanics

Answer 1

study of the human body at rest and in motion

Question 2

static biomechanics

Answer 2

examines bodies, masses, and forces at rest or moving at a constant velocity

Question 3

dynamic biomechanics

Answer 3

investigates body masses when speeding up or slowing down

Question 4

clinical biomechanics

Answer 4

focuses on improving an injured or disabled individual with everyday life things

Question 5

sport biomechanics

Answer 5

helps improve techniques for little improvement

Question 6

Giovani Alphonso

Answer 6

father of biomechanics

Question 7

linear motion

Answer 7

when all points of the body are moving in the same direction, speed, and distance

Question 8

angular motion

Answer 8

movement around a imaginary line

Question 9

general motion

Answer 9

when translation and rotation movements are combined

Question 10

cartesian coordinate system

Answer 10

system commonly used in biomechanics

Question 11

qualitative analysis of human movement require two important factors

Answer 11

techniques shown by the performer and performance outcome

Question 12

concepts related to kinetics

Answer 12

mechanical loads on the human bodies
tension and combined loads effects of loading
acute verses repetitive loads

Question 13

mechanical loads on the human body

Answer 13

forces that act upon a body or object, including those from gravity, the muscles, and external to the body

Question 14

compressive force

Answer 14

forces that tend to shorten or squeeze something, decreasing the volume

Question 15

tensile force

Answer 15

a force that tends to stretch or elongate something

Question 16

shear force

Answer 16

force acting on a substance in direction perpendicular to the extension of the substance

who do clinical biomechanics work with

Answer 17

works with injured/diseased people

Question 18

ergonomics

Answer 18

interaction between humans, the objects they use, and in the environment in which they function

Question 19

ergonomics are used to

Answer 19

prevent workplace injuries and improve the capacity to work after injury
