Types of Force Summary
+
A tensile force is an applied force that tends to pull an object apart.
+
A compressive force is an applied force that tends to compress an object.
+
Frictional force is the force resulting from two surfaces in contact, where one of
the surfaces is attempting to move with respect to the other surface.
+
Static-frictional forces are those frictional forces present when an object is
stationary, whereas kinetic-frictional forces are those frictional forces present
between two objects that are moving.
+
The magnitude of the frictional force is affected by the following:
-
Weight of the object being moved
-
Type of surface on the object being moved
-
Type of surface on which the object is moving.
+
Centripetal force is the force on an object moving in a circular path that is
directed towards the center of the path, whereas the centrifugal force is the
fictitious force that appears to be directed away from the center of the circular
path.
