Answer to Question 1

Agonist, antagonist, or synergist. Agonists are chiefly responsible for a movement. Antagonists oppose the agonists, keeping the movements smooth. Synergists provide additional force or stabilize the origin.

Answer to Question 2

Levers differ in the position of their fulcrum in relation to the applied force and the load. A first-class lever has the fulcrum positioned between the applied force and the load. Second-class levers have the fulcrum at one end, adjacent to the load, with the applied force at the other end. Third-class levers have the fulcrum at one end, the load at the other, and the applied force in the middle.
