Maine tumhari baat mani hai
maine manaya dil ko hai kaise
Ab se raho tum khush jahan bhi ho...
mera tumhara tha bhi kya vaise...
bhale doori rahe jitni nigaho se nigaho ki...
magar khabo ki duniya mai milunga tumse rozana...
Yahi tak tha safar apna tumhe hai lautkar jana...
kabhi mai yad au toh chale ana chale ana...

Answer:
Velocity is displacement by an object per unit time. Velocity is a vector quantity which means it has a magnitude and a direction.
Eg.100m/s North....100 is magnitude and north is direction....
Acceleration is rate of change of velocity means at which rate the velocity is increasing or decreasing.When acceleration decreases that phenomenon is retardation.Retardation is also called negative acceleration.
