Question

hi guys! I pls solve this ques from ch force and presure : motion

​

Answer 1

$\huge \tt {Answer:}$

A body is said to be in motion if it changes its position with respect to its surroundings.

✡Basically, there are three types of Motion, Translatory motion, Rotatory motion, and Vibratory motion. The translatory motion further divides into Linear motion, Random , and Circular motion

Answer 2

★ What is Motion ? ★

→ The change in the Position of an object with respect to its time and surrounding.

Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.

★Various Types of Motion ★

• Translatory Motion:- Motion in which all points of a moving body move uniformly in the same line or direction. Ex:- Man running.

• Linear Motion: A body or an object is said to be in linear motion when it travels along a straight line or along a curve in a plane. Ex:- An athlete running 100m in a track.

• Curvilinear Motion: The motion of an object moving in a curved path is called curvilinear motion. Ex:- A ball thrown into the air at an angle.

• Random Motion: The unpredictable type of motion in which an object moves in any direction(zig zag manner) and the direction changes continuously. Ex:- A footballer

• Rotatory Motion: The motion formed when an object rotates or spins on an axis. Ex:- Rotation of Earth.

• Rolling Motion: Rolling motion is the combination of rotation and translation of that object with respect to a surface. Ex:- A ball rolling on surface.

• Periodic Motion: The motion which repeats itself at an equal interval of time. Ex:- A swinging Jhoola

• Oscillatory Motion: The to and fro motion of an object from its mean position. Ex:- A pendulum

• Vibratory Motion: The motion in which a body moves to and fro from its mean position is called vibratory motion. Ex:- The strings of guitar.

• Multiple Motion: When a body/object posses more than one motion then it is called multiple motion. Ex:- Rolling down a ball through inclined then the ball will do the rotational motion as well as linear motion.
