Mechanics: Newton’s Laws and Application
normal force N … the force or the component of a force which a surface exerts on an object
with which it is in contact, and which is perpendicular to the surface
frictional force f … the force that opposes the motion of an object and which acts parallel to
the surface; f = μN
static frictional fs … the force that opposes the tendency of motion of a STATIONARY object
force relative to a surface. The static frictional force is a maximum (f smax) just before
the object starts to move across the surface. fs = μsN
kinetic frictional fk … the force that opposes the motion of a MOVING object relative to a
force surface; fk = μkN
force diagram a diagram that shows the relative magnitudes and directions of forces acting
on a body/particle that has been isolated from its surroundings
free-body This is a diagram that shows the relative magnitudes and directions of forces
