Constant Speed
An object with uniform motion has a constant speed and direction. This means it travels at the same velocity without speeding up or slowing down.
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.
When an object is speeding up or slowing down, it is experiencing acceleration. When it is turning, it is undergoing rotation or changing direction.
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then the object is speeding up.
The object is experiencing acceleration when it is speeding up or slowing down, and turning is an example of angular acceleration. Acceleration is the rate of change of velocity, either in speed or direction.

When it is stationary, or when the velocity is constant. If it is speeding up or slowing down, it has acceleration.

Acceleration being zero is equivalent to the statement that an object's velocity doesn't change.
Acceleration refers to the rate of change of an object's velocity, which can include both speeding up and slowing down. When an object accelerates, it can increase or decrease its speed depending on whether the acceleration is in the same direction as the velocity (speeding up) or in the opposite direction (slowing down).
The magnitude of acceleration is the rate at which an object's velocity changes over time. It is a measure of how quickly the object is speeding up or slowing down.
This would indicate negative acceleration, which would mean that the object in question is speeding up.
Positive acceleration occurs when an object's velocity is increasing over time, while negative acceleration (or deceleration) happens when an object's velocity is decreasing over time. Positive acceleration can be due to speeding up, turning, or changing direction, while negative acceleration is typically caused by slowing down or stopping.
A force such as friction, gravity, or a push/pull from another object can change the motion of a moving object by slowing it down, speeding it up, or changing its direction.
