... In the absence of external forces, an object at rest remains at rest and an object in motion continues in motion with a constant velocity. What does this statement tell us? 1. When no force is exerted on an object, the acceleration of the object is 0. 2. Any isolated object, the object that do not i ...

... Tension is the force in a string. Its direction depends on what it acts on. 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 alway ...
