Term
Force
Definition
The cause of acceleration of an object at a constant velocity.
Term
Contact force
Definition
The force between any objects that touch each other
Term
Field Force
Definition
"The force between two objects hat do not touch, such as gravity"
Term
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
Term
Action-Reaction Pair
Definition
When a pair of objects act on each other equally
Term
Weight
Definition
Mass x acceleration
Term
Normal force
Definition
The force of one surface to another…perpendicularly
Term
Static friction
Definition
The resistance of a surface against an object in the opposite direction of the applied force
Term
Kinetic friction
Definition
Friction between two objects that are moving
Term
Coefficient of friction
Definition
Fs or Fk divided by normal force
Term
