Mechanical Conecepta

Question 1

Rigid body

Answer 1

Simplifies by assuming no deformation

Question 2

Deformable body

Answer 2

Answer 3

Liquids and gasses
Flowing, air resistance

Question 4

Statics

Answer 4

At rest I’d uniform motion

Question 5

Dynamics

Answer 5

Being accelerated by forces

Question 6

Kinematics

Answer 6

Motion description
Measured in linear or angular terms, speed, stride, length

Question 7

Kinetics

Answer 7

Motion determination
Forces between or on objectives

Question 8

None principles of biomechanics - movement principles

Answer 8

Force- motion
Force- time
Inertia
Range of motion
Balance
Coordination continuum
Segmental interaction

Question 9

Projectile principles

Answer 9

Optimal projection
Spin

Question 10

Force- motion

Answer 10

Unbalances forces create or modify
Gravity
Ground reaction forces

Maintaining high speed

Question 11

Force- time

Answer 11

Changes in motion are not instant
Amount of time a force acts affects the resulting motion
Deceleration and landing

Question 12

Inertia

Answer 12

All objects resist changes to their state of motion
Newton’s first law

Question 13

Range of motion principles

Answer 13

• less ROM is most effective for low effort high accuracy movements
• isometric muscle action to follow fewest joint to move
• greater range of motion favors maximum efforts related to speed and overall force production

Question 14

Balance

Answer 14

Ability to control position relative to base of support
- stability
- mobility

Question 15

Coordination continuum

Answer 15

Timing of muscle actions depends on goal of the movement
- high force-more simultaneously
- low force or high speed - more sequential
- order of muscle activation

Question 16

Segmental interaction

Answer 16

Forces acting in a system can be transferred through links and joints
- open or closed chains

Question 17

Optimal projection

Answer 17

Effective range of angles for a specific goal
- compromise between horizontal and vertical velocity
- range or time of flight

Question 18

Spin

Answer 18

Affects flight pattern
Creates lift

Question 19

Qualitative movement diagnosis

Answer 19

Error and correction

Question 20
