Newton's 1st Law

Balanced Forces Particle Model

TermDefinition
Force an interaction between objects (push or pull)
Vector Free Body Diagram diagram showing all force vector acting on an object
Weight (Fw) non-contact force that acts towards the center of the massive object (planet like)
Normal Force (Fn) contact force that acts perpendicular to the surface due to the compression of atoms in the surface.
Friction Force (Ff) contact force that acts parallel to the surface but opposite to the motion. atoms are sheared and crunched
Tension Force (Ft) Contact force along a rope, string, cable, chain...
Spring Force (Fk) Contact force along the spring due to the compression or expansion of a spring.
Newton [N] Unit of force
Net force (Fnet) The sum (addition) of all forces acting on an object
Inertia the property of matter that resists a change in motion
Balanced Forces Fnet=0, no change in motion, rest of constant motion
Unbalanced Forces Fnet= #, change in motion, acceleration
terminal velocity an object falling at a constant velocity
mass amount of inertia in an object [kg]
equilibrium balanced
momentum inertia in motion [kg*m/s]
Applied Force (Fa) general label for forces that causes a push or pull
Thrust Force (F thrust) force caused by rockets/ exhaust
Buoyant Force (Fb) Force caused by floating
Lift Force (Fl) Force applied to bottom of wings to fly
