Movement Analysis (3.7)

Question 1

What are the six Anatomical Positions?

Answer 1

Flexion: Movement at the joint resulting in the angle between two joints

Extension: Movement at a joint resulting in an increase in angles between two bone

Abduction: Movement away from midline of the body

Adduction: Movement towards midline of the body

Anterior: Front face of the body

Posterior: Back face of the body

Question 2

What are the Types of Motion within Kinematics?

Answer 2

Linear Motion: motion of a body in a straight line

Angular Motion: motion of all parts around a fixed point

General Motion: Linear + Angular

Projectile Motion: A body that moves through the air

Question 3

What are the 6 Factors Affecting Projectile Motion?

Answer 3

Velocity of Release: harder a ball is thrown the further it goes due to transfer of momentum

Angles of Release: Coaches ensure correct AoR

Height of Release: Higher the point of release above ground, further it will go

Shape: streamlined shapes travel more efficiently in air and travel further due to less drag

Air Resistance: When a projectile moves through air it creates a drag force

Spin: can change the parabola of trajectory

Question 4

Kinematics

Answer 4

Mass: amount of matter that makes up an object

Momentum: amount of motion by a moving object

Inertia: To stay in motion unless acted upon by an external force

Question 5

what are three Types of Forces?

Answer 5

1. Forces produced from within the body due to muscular contraction
2. Forces applied to equipment i.e. cricket bat
3. Forces acted upon a body due to interaction with environment
