Yes.the body can have multiple motions at the same time for example if you roll down a ball through inclined then the ball will do the rotational motion as well as linear motion.

$How can a single body have multiple motions? Explain with the help of examples.$

$First, we will take a look at different types of motion :-$

There are different kinds of motion:

$(i)Translatory motion :$ A body moving along a line where all points of the body move along the same path is said to be in linear or translatory motion.

Translatory motion is of two types :

$a. Rectilinear motion :$ If the body moves in a straight line ,its motion is said to be rectilinear.

E.g.,A car moving along a straight road ,movement of a bus on a deserted highway road.

$b. Curvilinear Motion :$ If the body moves along a curved line ,its motion is said to be curvilinear.

E.g., a car taking a turn, a ball thrown at an angle follows a curved path before reaching the ground.

$(ii) Rotatory or Circular Motion:$ The motion of a body in a circular path around a fixed point or a fixed axis is known as circular motion.

E.g.,The motion of earth around its own axis ,movement of ceiling fans, tyres ,giant wheel, and merry-go-round.

$ (iii) Periodic Motion:$ When a body moves to and fro about a fixed point and the motion is repeated at equal intervals of time, the motion is said to be periodic.

E.g., A pendulum of wall clock, the motion of child on a swing, heartbeat, motion of planets around the sun.

$ (iv) Random Motion:$ When a body moves in different directions and does not have a fixed path , it is called random motion.

E.g.,the flight –path of an insect, the flow of water in rivers ,movement of atoms and molecules in liquids and gases.

Now, we will come to the main question.

$Yes, a body can have multiple motions at a same time $

Here are some examples :

$(i).A running vehicle executes both translatory and rotatory motion. The wheels of the vehicle executes rotatory motion. The vehicle itself execute translatory motion.$

$(ii).A ball rolling on ground executes both translatory and rotatory motion.In rolling , it is executing rotatory motion and in moving from its original position , it is executing translatory motion.$
