Force is simply, an interaction of an object to
another by a push or pull. Friction force is when an object wields force by two
objects being pressed together; it may also oppose the object’s direction. This
force has two types: sliding and static friction. Sliding friction is simply
the force exerted when an object slides in a surface. Static friction is when
both objects are at rest and an external force affects and creates a motion of
one of the objects causing that object to create a motion to the other.
