Movement Analysis Flashcards
Define first class lever
The lever system where the fulcrum occurs between the load and the effort
Define second class lever
The lever system where the load is placed between the fulcrum and the effort
Define third class lever
The lever system where the effort is applied between the fulcrum and the load
Define fulcrum
The point at which the lever pivots
Define load
The weight placed upon the lever
Define effort
The force required in order to move the load placed on a lever
Define load arm
The distance between the fulcrum and the load
Define effort arm
The distance between the fulcrum and the effort
Define mechanical advantage
A reduction in the effort required to move a load in first and second class lever systems
Define mechanical disadvantage
An increase in the effort required to move a load and an increase in the speed that that movement can occur in third class lever systems
Define frontal plane
The place which splits the body into front and back
Define transverse plane
The plane which splits the body into top and bottom
Define Sagittal plane
The plane which splits the body into left and right
Define longitudinal axis
The axis of rotation which operates vertically from her head to the feet
Define transverse axis
The axis of rotation which passes horizontally from the left side of the body to the right
