define motion and kinds of motion with suitable examples and Define laws of motion.
Answers
define motion:-
- Motion is the change of position of a body with time, with respect to a stationary body.
Motions are of three types:
TRANSLATORY MOTION - if a body moves as a whole, such that every part of the body travels through the same distance in a given time, the body is in translatory motion.
Translatory motion is of two types-
RECTILINEAR- if a body moves along in a straight line it is said to be in rectilinear motion. Eg. A car moving along a straight line.
CURVILINEAR- if a body moves along a curved line, it is said to be in curvilinear motion. Eg. Car at a U-turn.
----------------------------------------------
CIRCULAR MOTION - the motion of a body in a circular path along a fixed point or a fixed axis is known as circular motion.
Circular motion are of two types:
ROTATION- if the body turns without shifting its position from one place to another, its motion is called rotation.
REVOLUTION- if the body moves as a whole around in a circular path, the motion is known as revolution.
----------------------------------------------
OSCILLATORY MOTION- when a body moves to-and-fro about a fixed point, it is said to be in oscillatory motion or vibratory motion.
Oscillatory motion is of three types:
REPETITIVE- if the same motion occurs again and again, it is said to be repetitive motion.
PERIODIC- a repetitive motion that takes place at regular intervals of time is periodic motion.
NON-PERIODIC- motion that is not periodic is known as non-periodic motion.

define laws of motion?
There are three types of laws of motion :
- Newton's first law of motion
- Newton's second law of motion
- Newton's third law of motion
★ Newton's First Law of Motion :
- A body in rest will remain at rest,and a body in motion will continue in motion in a straight line with uniform speed, unless it is compelled by an external force to change its state or of uniform motion.
★ Newton's Second Law of Motion :
- The rate of change of momentum is directly proportional to the applied force,and takes place in which the force acts.
★ Newton's Third Law of Motion :
- Whenever one body exerts a force on another body,the second body exerts an equal and opposite force on the first body.
OR
- To every action there is an equal and opposite reaction.

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.
