no, deceleration.
When an object is speeding up or slowing down, it is experiencing acceleration. When it is turning, it is undergoing rotation or changing direction.
Deceleration
A negative acceleration indicates that an object is slowing down. It means that the velocity of the object is decreasing over time.
An object that is accelerating is either speeding up or slowing down. If the acceleration is in the same direction as the velocity, the object is speeding up. If the acceleration is opposite to the velocity, the object is slowing down.
If an object is slowing down, it is experiencing negative acceleration, also referred to as deceleration. This means that the object's velocity is decreasing over time.
This would indicate negative acceleration, which would mean that the object in question is speeding up.
Negative acceleration, also known as deceleration.
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
This is a moving object that is slowing down.
Acceleration is the change of velocity, with direction. Therefore slowing down is a change in veolcity, so is considered to be acceleration (just negative acceleration).
Acceleration becomes negative when an object is slowing down or decelerating. This occurs when the direction of the acceleration is opposite to the direction of the object's velocity.
