1.	Define acceleration and give its SI unit. When is acceleration of a body negative? Give two examples of situations in which acceleration of the body is negative.
Answer» ACCELERATION can be defined as the RATE of CHANGE of VELOCITY.. It is a vector quantity .. Its SI unit is meter/second^2. When the velocity of an object DECREASES,then the object is said to be moving with negative acceleration.. An example of negative acceleration would be a car breaking or decelerating.
