Answers
1
What does the preparation phase of a skill movement involve?
Preparing yourself to perform the skill
Finishing off the skill
Execution of the skill
Performing the skill itself
2
Negative acceleration would see:
A decrease in speed
A maintenance in speed
Change in direction
An increase in speed
3
Angular motion is measured in:
Length
Degrees
Circles
Lines
4
What are 2 ways in which tennis rackets have been improved resulting in biomechanical advantages?
Improved string material and heavier frame
Heavier frame and reduction of strings
Lighter frame and improved string material
Lighter frame and different colours
5
What are the two main roles of biomechanics?
To improve athlete performance and reduce sports injuries
To improve participation and increase motivation
To improve the relationship between athlete and coach
To increase injuries and reduce athlete pay
6
What is biomechanics?
Study of motion & the effects of forces relative to the body
Study of biological mechanics
Some thing you do in PE Studies
Study of sports
7
What is general motion?
A combination of linear and angular motion
The rotary movement about an axis
Movement is linear but object moves through a curved trajectory
Movement is linear and occurs through a straight line
8
Linear motion is measured in:
Length
Circles
Degrees
Lines
9
Angular motion occurs when objects:
Rotate in a linear motion
Form an angle
Move in the same direction at the same speed
Turn about an axis of rotation
10
Excluding the playing surface, what other factors can impact the way athletes absorb force through the body?
Distance and time
Technique and equipment
Linear motion and angular motion
Internal and external forces
11
An example of an external force is:
Use of equipment
Air resistance
Degrees
Competition intensity
12
What is an external force with relation to biomechanics?
Structures of the body that interact to produce movement
The interaction between the body and the environment
The ‘hammer’ moving around the athlete during a hammer throw
Where movement is along a straight line
13
What type of motion is a bowling ball travelling down the alley?
Angular
Acceleration
General
Linear
14
An example of an internal force is:
The impact of gravity
Spin on a soccer ball
Force produced by our muscles
The weight of a soccer ball
15
What are 2 ways in which AFL boots have been improved resulting in biomechanical advantages?
Lightweight material and the addition of sprigs/studs
Heavier material and less comfortable
More comfortable and the removal of sprigs/studs
Different colours and the addition of sprigs/studs
16
What are the 3 main types of motion?
Distance, time and velocity
Angular, general and inertia
Horizontal, transverse and sagittal
Linear, angular and general
17
What are the 3 main axis of rotation?
Medial, longitudinal, horizontal
Frontal, side and angular
Speed, angle and time
Velocity, time and distance
18
What is linear motion?
A result of the interaction between the body and the environment.
Structures of the body that interact to produce movement
Wheremovement is along a straight line
A combination of linear and angular motion
19
What are the 3 main types of biomechanical analysis?
Game, testing and practice
Field, practice and intensity
Laboratory, field and competition
Field, training and game
20
Positive acceleration would see:

22
What is an internal force with relation to biomechanics?
The interaction between the body and the environment
The ‘hammer’ moving around the athlete during a hammer throw
Where movement is along a straight line
Structures of the body that interact to produce movement
23
Standing in anatomical position, where is your centre of gravity?
Shoulders
Belly button
Head
Feet
24
What are the 3 phases of movement?
Preparation, execution and follow through
Beginning, middle and end
Start, execution and completion
Preparation, validation and follow through
25
