no, deceleration.
Deceleration
This would indicate negative acceleration, which would mean that the object in question is speeding up.
When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.
Negative acceleration, also known as deceleration.
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).
It is called deceleration.
The acceleration is opposite the direction the object is moving, so the acceleration is negative and southward.
Acceleration - as defined in physics - means "change of velocity".
Acceleration. Acceleration is change in velocity. Velocity is its speed and direction. So when one of these things changes, it is undergoing acceleration. Acceleration can be the object speeding up, slowing down, turning right, turning left, etc. Deceleration is lowering the rate of change. You are experiencing no change if you are moving in a straight line at a constant speed.
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.
It slow down, and eventually reverse direction.
This is a moving object that is slowing down.
