Force and Motion
... Normal reaction is the force acting on an object by the surface in contact with the object. It is always perpendicular to the surface. Friction arises whenever an object slides or tends to slide over another object. It always opposes or prevents motion. Fluid friction, e.g. air resistance, is the fr ...

Forces Cause Changes in motion
... The NET FORCE acting on an object is the sum of all the force acting on it. The net force on an object is zero if the forces acting on it tend to cancel each other out.
