1.	What is Acceleration? N name its types!
Answer» ation of an OBJECT is DEFINED as the rate of change in velocity of the object.Acceleration is a vector quantity. (1) POSITIVE acceleration– If the acceleration is ACTING in the direction of motion of a body, the velocity of a body will increase with time. then the acceleration of a body is positive.(2) Negative acceleration– If the acceleration is acting opposite to the direction of motion of a body, the velocity of a body will decrease with time. then the acceleration of a body is negative. (Negative acceleration is also called RETARDATION or deceleration). (3) Zero acceleration– If a body is moving with a constant velocity, then the acceleration of a body is zero.
