1.	What do you mean by acceleration? Detailed answer needed as it's of 100 points
Answer» ation of an object is defined as the RATE of the change of velocity ━━━━━━━━━━━━SI UNIT isCGS UNIT is━━━━━━━━━━━━━━If the final velocity of a moving BODY is greater than the initial velocity then ACCELERATION is said to be positive.If the final velocity of a moving body is less than the initial velocity then acceleration is negative. Then it's called retardation or negative acceleration.
