Test 1

Question 1

What is biomechanics

Answer 1

Forces acting on living systems
- effects of those forces (movement, deformation, growth, injury)

Question 2

Goal of biomechanics

Answer 2

Measure, describe, analyze, and assess movement

Question 3

Rigid bodies

Answer 3

Does not deform when force is applied

Question 4

Deformable bodies

Answer 4

Considers deformation of system when force is applies

Question 5

Defo

Question 6

How can biomechanics improve performance

Answer 6

• better skill technique
• better equipment
• better training techniques

Question 7

How can biomechanics prevent and rehabilitate injuries

Answer 7

• more effective techniques to reduce injury
• better equipment designs to reduce injury
• better rehab practices

Question 8

What is kinematics

Answer 8

Concerned w description of motion
-not concerned w forces causing movement

Acceleration

Question 10

Rectilinear motion

Answer 10

All points on a body move the same distance in the same time in a straight line

Question 11

Curvilinear motion

Answer 11

Question 12

Angular motion

Answer 12

Body moves in circles around an axis

Question 13

General motion

Answer 13

Combination of linear and angular motion

Question 14

What is distance

Answer 14

Length of an objects path from initial to final position

Question 15

What is displacement

Answer 15

Straight line distance from initial to final position
-positive moves up or right
-negative moves down of left
