What does decceleration mean?
Deceleration is the opposite of acceleration. It means decreasing speed and can be measured as negative acceleration.
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 does not always mean that an object is slowing down. Negative acceleration just means that there is a decrease in the object's velocity, which could be a result of the object changing direction or speeding up in the opposite 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.

What does a stand for in physics?
In physics, "a" typically stands for acceleration, which represents the rate of change of velocity of an object over time. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed).
Is deceleration mean negative of acceleration?
Deceleration is the negative of acceleration when the object is slowing down. However, it's important to note that deceleration is actually a type of acceleration, where the object is accelerating in the opposite direction of its initial velocity.
What does it mean when acceleration is large?
When acceleration is large, it means that the rate of change of velocity is significant. This could indicate that an object is speeding up or slowing down rapidly. The larger the acceleration, the quicker the change in velocity.
Can a body accelerate without speeding up or slowing down?
Yes, a body can accelerate without changing its speed if it changes direction but not its speed, such as when moving in a circular path at a constant speed. In this case, the body is still accelerating because its velocity (direction of motion) is changing.
What does mean the velocity remains constant?
When an object's velocity remains constant, it means the speed and direction of the object's motion do not change. This implies that the object is moving at a consistent rate without speeding up, slowing down, or changing course.
What does constant velocity mean?
It means moving at a constant speed ... not speeding up or slowing down ... and in a straight line.
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.
