$\huge\boxed{\fcolorbox{black}{pink}{Motion}}$

Motion is a process in which a body changes it's position in a certain time.

There are three basic types of motion-

• ◾Linear Motion.
• ◾Oscillatory Motion.
• ◾Rotatory Motion.

$\huge\boxed{\fcolorbox{black}{pink}{Linear\:Motion}}$

◾Linear Motion is often called Rectilinear Motion.

It is only one dimensional in a straight line.

◾Linear Motion is most basic of all motions.

$\huge\boxed{\fcolorbox{black}{pink}{Oscillatory\:Motion}}$

◾Oscillatory Motion is "to and fro motion" of any object.

◾It is repetitive variation of motion.

◾Alternating current is an example of Oscillatory Motion.

$\huge\boxed{\fcolorbox{black}{pink}{Rotatory\:Motion}}$

◾Rotary Motion is a motion in which object move from the axis to the axis.

◾Motion of earth, fan e.t.c are examples of Rotary Motion.

◾It is often known as Circular motion.

Answer 2

Explanation:

There are different types of motion: translational, rotational, periodic, and non periodic motion. Translational Motion. A type of motion in which all parts of an object move the same distance in a given time is called translational motion.

★ Translational motion is the motion by which a body shifts from one point in space to another. One example of translational motion is the the motion of a bullet fired from a gun. An object has a rectilinear motion when it moves along a straight line.

★ The motion of a rigid body which takes place in such a way that all of its particles move in circles about an axis with a common angular velocity; also, the rotation of a particle about a fixed point in space.

★ Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.

★ Non-periodic motion : The motion which does not repeat itself after regular interval of time is called non-periodic motion. Examples : A footballer running on a field, application of brakes in a moving vehicle, a ball rolling down the ground gradually slows down and finally stops, motion of tides in the sea, etc.
