Question

expain different type of motion?​

Answer 1

Answer:

Types Of Motion. There aredifferent types of motion: translational, rotational, periodic, and non periodicmotion. 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 can be of two types, rectilinear and curvilinear.

Explanation:

➯What is Motion

When a body does not change its position with time, we can say that the body is at rest, while if a body changes its position with time, it is said to be in motion.

➯Types Of Motion

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. Examples are vehicles moving on a road, a child going down a bird flying in the sky. Translational motion can be of two types, rectilinear and curvilinear. Table shows the differences between rectilinear and curvilinear motions.

➣Examples of translational motion: a child going down a slide.

➯Rotational Motion

When an object moves about an axis and different parts of it move by different distances in a given interval of time, it is said to be in rotational motion. Examples of objects undergoing rotational motion are blades of a rotating fan, merry-go-round, blades of a windmill. When an object undergoes rotational motion, all its parts do not move the same distance in a given interval of time. For example, the outer portion of the blades of a windmill moves much more than the portion closer to the centre.

➯Periodic Motion

A type of motion that repeats itself after equal intervals of time is called periodic motion. Examples of objects undergoing periodic motion are the to and fro motion of a pendulum, the Earth (rotating on its axis), the hands of a clock, the blades of a rotating electric fan, and the plucked string of a guitar.

➯Non-periodic Motion

A motion that does not repeat itself at regular intervals or a motion that does not repeat itself at all is called non-periodic motion. Examples of non-periodic motion are a car moving on a road, a bird gliding across the sky, and children playing in a park. In everyday life, we observe more than one type of motion, like

➾Birds gliding across the sky (translational and non periodic).

➾Rotation of the Earth on its axis (rotational and periodic).
