Acceleration is change in velocity. It is a vector, so some direction is choosen as positive and the opposite direction as negative. Then you have two possibilities;(1) the object is increasing its speed in the negative direction. (2) the object is decreasing its speed in the positive direction. Both of these give negative acceleration. For example; if up is choosen as positive then acceleration due to gravity is always negative because when a projectile is projected up with some initial velocity it decreases its speed on the way up. But on the way down its increasing its speed, in the negative direction.

An object that is accelerating maybe slowing down or speeding up?
yes the acceleration can take a negative value. for example an object with an accleration of -2 ms-2 would be slowing down. However this is normally called deceleration.
Why centripetal accleration is measured in grams?
It is not. It is measured in metres per second ^2.
What is the equation for accleration?
Acceleration = change in velocity/time for the change in the direction of the change.
What law of motion says that unbalanced forces cause accleration?
Newton's 2nd law of motion.
When a falling object has reached its teminal velocity its accleration?
When the velocity stops changing, then, by definition, the acceleration is zero.
Disscuss the relationship between velocity and accleration?
accleration is the speed. Velocity is when you know the speed of an object and its direction.
Who are the founders of accleration due to gravity?
Mianus
What are units for accleration?
kg m/s2
What are two types of accleration?
Changes in speed or direction
Formula constant accleration?
Acceleration with respect to time = a , where 'a' is a constant.
What is acceleation?
if that is a typo and you mean accleration it means going fast

What two things must you include when describing displacement?
a vector and accleration
Automatic or standard veichles have faster acceleration?
automatic has faster accleration
What will cause an engine to bog out on accleration?
clogged up catylatic converter.
Is equivalent to an objects mass times accleration due to gravity?
Weight.
Could a bad ball joint cause vibration on accleration?
Yes
