Term
 Field Force
Definition
 "The force between two objects hat do not touch, such as gravity"

 Force diagrams
Definition
 Diagrams with vectors representing all forces in a system
Term
 Inertia
Definition
 The “laziness” of an object to change velocities
Term
 Net External Force
Definition
 "All of the forces together…many of ours have canceled out…including gravity and normal force, and sometimes friction and applied force"
Term
 Equilibrium
Definition
 Whenever an object is at rest or progressing at a constant velocity. All of the forces cancel out
