When acceleration and velocity vectors are pointing in opposite directions the object is?
This would indicate negative acceleration, which would mean that the object in question is speeding up.
How can an object be accelerating if it's slowing down?
Acceleration doesn't mean "speeding up". It only means that the speed or direction of motion, or both, are changing. Speeding up is positive acceleration in the direction you're moving. Slowing down is negative acceleration in the direction you're moving, or positive acceleration in the opposite direction.
Does a negative acceleration always mean that an object is slowing down?
No. A negative acceleration could mean a change in direction
Does it mean a skydiver is slowing down if the acceleration of the skydiver decreases as falling progresses?
No.Acceleration is a measure of the rate of change of velocity (speed & direction). If acceleration is decreasing (but still above zero) then this means that the rate at which the speed is increasing in this direction is decreasing.As long as the downward acceleration is greater than zero then the skydiver's speed is still increasing.Once terminal velocity is reached then downward acceleration will equal zero (speed is constant).If the downward acceleration falls below zero (as will happen once his parachute is deployed for instance) then this means he is slowing down.
Can a body accelerate without speeding up or slowing down?
Yes. Acceleration does NOT mean 'speeding up', or even 'slowing down'.'Acceleration' means any change in the speed or the direction of motion. Soif you take a curve at constant speed, there is acceleration present while yourdirection is changing around the curve.An object in a closed curved path ... like a race car in a circular or oval track, or a planetor moon in a closed curved orbit ... is ALWAYS accelerating, even if its speed never changes,because its direction is constantly changing.

Is deceleration mean negative of acceleration?
acceleration is the speeding up of some type of matter. deceleration is the slowing down of some type of matter
What does mean the velocity remains constant?
there is no acceleration if the body is moving with constant velocity
Is there such a thing called decelaration?
Technically no. "Deceleration" is a term used by many people to describe an object slowing down. However, the physics definition of acceleration is the change of velocity or direction. This means that acceleration can mean either speeding up, slowing down, or changing direction. While it is understood what "deceleration" means, it is a misused term.
What does constant velocity mean?
It means moving at a constant speed ... not speeding up or slowing down ... and in a straight line.
Can velocity be 0 but speed not 0?
Speed and Velocity are two words that mean the same. You may mean, "Can Velocity be 0 but acceleration not 0". Yes, this occurs when a moving object is changing direction (say from moving forwards to moving backwards) or is just about to move or, at that very instant has just come to a halt. In all these cases, speed /velocity is zero but the body is accelerating. Don't forget, the word acceleration is also used when an object is decelerating (slowing down).
What does rallentando mean?
slowing down till the end
What is decelerating?
DECELERATION,SLOW DOWN=TO REDUCE SPEED,OR MAKE SOMETHING DO THIS
