Front 5

Lever and it's parts

Back 5

Rigid structure that moves about a Fulcrum. One side is the Effort, One side is the Load/Resistance

Front 6

Leverage and two types

Back 6

Mechanical advantage is smaller effort moving heavier load

Mechanical Disadvantage is greater effort moving smaller load. Which is what allows fast pitching
