(a) Rectilinear motion : The motion of a body in a straight line is known as rectilinear motion. It is also known as translational motion. For example, A man/car moving on the straight road, a ball dropped from a height, a train running on the straight track will trace rectilinear path.
(b) Curvilinear motion: When an object moves along a curved path, then it is said to be undergoing a curvilinear motion. A car taking a turn is an example of curvilinear motion.
(c) Rotatory motion: A body is said to be in rotatory motion if it moves about a fixed axis. A spinning wheel is an example of rotatory motion. It moves in a circular path about a fixed axis. Similarly, the rotating fan is another example of rotatory motion.(d) Circulatory motion: Circulatory motion is the movement of the body in a circular path when the speed remain constant but there is continuous direction of the motion of the object, Rotation of of moon around the earth is the example of uniform circular motion.
