Describe the autonomous stage of learning.
High skill levels, few errors, ability to detect and correct own errors, and automatic performance. ## Footnote Allows focus on other aspects, like tactical awareness.
26
What is augmented feedback?
External feedback from an outside source. ## Footnote It can improve performance by providing additional information.
27
What is knowledge of results in feedback?
Information about the outcome or result of a performance. ## Footnote It helps performers understand their success.
28
What is knowledge of performance in feedback?
Information about the technique or characteristics of the movement pattern. ## Footnote It aids in refining technique.
29
Define Newton's first law of motion.
A body continues in a state of rest or uniform velocity unless acted upon by an external force. ## Footnote This is known as the law of inertia.
30
What is Newton's second law of motion?
A force applied to an object produces a change in motion in the direction of the applied force, proportional to the size of the force. ## Footnote Equation: Force = Mass x Acceleration.
31
Define Newton's third law of motion.
For every force exerted by one body on another, there is an equal and opposite force exerted by the second body on the first. ## Footnote Known as the law of action-reaction.
32
What is a force?
A push or pull that alters the state of motion of a body, measured in Newtons. ## Footnote Forces can change shape or move objects.
33
What is friction?
Opposition to motion when two surfaces come into contact. ## Footnote It can be adjusted based on the desired outcome.
34
What is drag in biomechanics?
A force opposing the direction of motion when an object moves through air or water. ## Footnote It is affected by air density, cross-sectional area, and speed.
35
Define gravitational force.
The force of attraction between two bodies, causing objects to fall towards the center of the Earth. ## Footnote It affects all objects thrown or projected into the air.
36
What is mass?
A measure of the amount of matter in an object, measured in kilograms. ## Footnote Mass is related to inertia.
37
What is weight?
The force exerted on a body by gravity, measured in Newtons. ## Footnote Weight = Mass x Gravity.
38
Define inertia.
The resistance of a body to a change in its state of motion. ## Footnote Greater mass leads to greater inertia.
39
What is momentum?
A measure of the amount of motion a body has, calculated as mass times velocity. ## Footnote Momentum is important in sports, especially in collisions.
40
What is the formula for calculating momentum?
Momentum (Kgm/s) = mass (Kg) x velocity (m/s) ## Footnote Momentum is directly proportional to both mass and velocity
41
What happens to the momentum of an object that is not moving?
It has zero momentum because it has no velocity. ## Footnote This highlights the importance of motion in momentum.
42
What is the summation of momentum in sports?
Adding up the momentum of all sequences of movement involved in an action like a throw, strike, or jump. ## Footnote Effective summation of momentum maximizes force development.
43
List the principles for effective summation of momentum.
* Provide a stable base or stabilize body parts * Use as many body parts as possible * Start with larger body parts and progress to smaller body parts * Transfer body parts when previous body part is at maximal velocity * Use a follow-through ## Footnote These principles ensure maximal force transfer.
44
True or False: Momentum is conserved when objects collide.
True ## Footnote Total momentum of an isolated system remains constant during collisions.
45
What is impulse in relation to momentum?
Impulse is equal to the change in momentum of an object. ## Footnote Impulse = Force x time.
46
How can impulse affect performance in sports?
It can create a larger force or reduce peak force by spreading force over a longer period. ## Footnote This manipulation can reduce injury risk.
47
What does angular motion refer to?
The motion of objects as they rotate around an axis. ## Footnote Common in sports like gymnastics and figure skating.
48
Define torque.
Torque is the rotational equivalent of force, calculated by force x lever arm. ## Footnote It causes an object to rotate around an axis.
49
What is angular momentum?
The amount of angular motion possessed by a body, calculated as angular momentum = moment of inertia x angular velocity. ## Footnote It helps athletes control spins and movements.
50
What is moment of inertia?
A measure of how the mass of an object is distributed relative to its axis of rotation. ## Footnote It affects how easily an object can start or stop rotating.
51
How is angular momentum conserved in flight?
Angular momentum remains constant from takeoff until landing. ## Footnote Changes occur in moment of inertia and angular velocity.
52
What are the key kinematic concepts in human movement?
* Distance * Displacement * Speed * Velocity * Acceleration * Projectile motion ## Footnote Kinematics describes motion without considering forces.
53
What is linear motion?
When all body parts are moving at the same speed and direction along a curved or straight line. ## Footnote It includes concepts like distance and displacement.
54
Define acceleration.
A measure of how quickly an object changes velocity, measured in m/s². ## Footnote It can be positive, negative, or zero.
55
What is the difference between angular distance and angular displacement?
Angular distance is the sum of all angular changes, while angular displacement is the difference between initial and final angular positions. ## Footnote Direction is also considered in angular displacement.
56
What factors influence projectile motion?
* Angle of release * Speed of release * Height of release ## Footnote Coaches can manipulate these for optimal performance.
57
What is static equilibrium?
When the body or object is not moving or rotating. ## Footnote This is crucial for maintaining balance.
58
What factors affect stability?
* Base support * Center of gravity * Body mass * Friction ## Footnote Stability is essential for good performance in sports.
59
What are the three parts of a lever?
* Axis (fulcrum) * Resistance (weight) * Force (effort) ## Footnote Different classes of levers have different arrangements of these parts.
60
What characterizes first-class levers?
The axis is between the force and resistance (FAR). ## Footnote Examples include muscle pairs working around joint axes.
61
Describe second-class levers.
The resistance is between the force and the axis (ARF). ## Footnote Few examples exist in the human body.
62
What defines third-class levers?
The force is between the resistance and the axis (AFR). ## Footnote Most common type in human movement, allowing greater range of motion.
63
What is mechanical advantage?
The ratio of the force arm to the resistance arm in a lever system. ## Footnote A lever with a longer force arm requires less effort to move a resistance.
64
How does lever length affect performance?
Longer levers increase range of motion and velocity but require greater force. ## Footnote This is why junior sporting equipment is often modified.
