Question

27. Define acceleration and give its SI unit. When is acceleration of a body
negative?​

Answer 1

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.
