what is the difference between velocity and acceleration
please give me right answer
or koi bhi I don't know likh kr mat chodh dena samjhe

Step-by-step explanation:
The rate of change of your position with time defines your velocity. In everyday language, velocity means the same thing as speed. However, in physics, there is an important distinction between the two terms. Speed is a “scalar” quantity, and it’s measured in units of distance/time, so in meters per second or miles per hour. Velocity is a “vector” quantity, so it has both a magnitude (the speed) and a direction. Technically, saying you’re traveling at 5 meters per second is a speed and saying you’re traveling at 5 meters per second towards the north is a velocity, because the latter has a direction too.
Acceleration is the rate of change of velocity with time. Like velocity, this is a vector quantity that has a direction as well as a magnitude. An increase in velocity is commonly called acceleration while a decrease in velocity is sometimes termed deceleration. Technically, since velocity includes a direction as well as a speed, a change in direction at a constant speed is still considered acceleration.
