What it is?
In
linear motion
,

,.
In
Circular motion
, Where
an object travels along in a circular path
an object covers equal distance in equal intervals of time
an object travels along a straight line but varying in its speed

, When
an object travels along in a circular path
an object covers equal distance in equal intervals of time
an object travels along a straight line but varying in its speed
the object moves along in a straight line
.
In
Non-uniform motion
,
an object travels along a straight line but varying in its speed
the object moves along in a straight line
an object travels along in a circular path
an object covers equal distance in equal intervals of time
.
