RECTILINEAR MOTION

1. Mechanics is the branch of physics which deals with the cause and effects of motion of a particle, rigid objects and deformable bodies etc. Mechanics is classified under two streams namely Statics and Dynamics. Dynamics is further divided into Kinematics and Kinetics. 

2.  MOTION AND REST 

 Motion is a combined property of the object and the observer. There is no meaning of rest or motion without the observer. Nothing is in absolute rest or in absolute motion.    

 An object is said to be in motion with respect to a observer, if its position changes with respect to that observer. It may happen by both ways either observer moves or object moves.  

3. RECTILINEAR MOTION 

 Rectilinear motion is motion, along a straight line or in one dimension. It deals with the kinematics of a particle in one dimension.
