- - - - friction
        
        when 2 objects make contact with each other always in the opposite direction
        
        increased
        
        studs on football boots to prevent slipping
        
        decreased
        
        streamline blades on roller-skates making less surface area
      - drag/air resistance
        
        acts in the opposite direction to a projectiles path slowing distance and velocity
        
        swimmer shaving their body to decrease drag
      - fluid resistnce
        
        drag but in water. same rules apply
      - weight
        
        mass x gravity
        
        the force that the gravity exerts apon an object
      - gravity
        
        pulls object down to earth
  - - - high mass
        
        higher inertia, more force needed
        
        shot put
      - low mass
        
        small inertia, less force needed to displace
        
        tennis ball
  - - - angular
        
        angular motion refers to motion that occurs when a body moves along a circular path
        
        external: on a piece of equipment
        
        eg: a gymnast rotating around the bar
        
        internal: body joint axis
        
        eg: rotator cuff when swimming
      - linear
        
        linear motion refers to motion that occurs in a straight line
        
        eg: running or jumping
      - general
        
        a combination of both linear and angular to create motion
        
        eg: running in a straight line is caused by the internal rotation of knees and arms
  - - - An object is equal to it's mass x acceleration
    - - Everything has an equal and opposite reaction
        
        Eg: The force of the baseball making the bat go back
    - - An object will remain still unless a force is acted apon it
        
        Eg: A basketball will remain still on the ground unless it is picked up
  - - - conservation of momentum
        
        when two objects/bodies combine the combined momentum is conserved
        
        two athletes; ones heavier they fall the way the heavier one is going
      - linear momentum
        
        mass x velocity
      - force summation aka summation of momentum
        
        the correct timing and sequencing of body segments and muscles through rage of motion
      - angular momentum
        
        the amount of rotational motion an object has
  - - - cricket ball striking the bat
- - - - outside feedback usually given by a coach or person evaluating an individuals skill
    - - inside feedback given internally from individual to themselves
  - - - associative stage
        
        athlete understands the fundamentals of the skill and is in the process of refining the skill. They experience fewer errors and can detect some of them on their own.
    - - autonomic stage
        
        At this point the skill is well learned. The athlete performs the skill automatically without having to focus on execution. There are few errors and athletes can detect and know how to correct them. They can concentrate more on other aspects of the game.
    - - cognative
        
        athlete is attempting to understand the basic task.
  - - - a sequenced practice and rest time in which rest is much less than practice
    - - spaced practice which practice is equal or less than rest
    - - a practice sequence organised around the task, performed repeatedly and uninterrupted
    - - a random unsequenced practice across all trials
