An object that is accelerating may slow down, speed up, or change direction.
When forces do not balance, the object will experience acceleration or changes in motion. If the net force is not zero, the object will accelerate in the direction of the higher force.
When an object is accelerating, it can experience changes in velocity, either speeding up or slowing down. Additionally, the object can also experience a change in direction as it accelerates. The forces acting on the object may also change in magnitude and direction.

You can tell if an object is accelerating if its speed is changing or if its direction of motion is changing. Acceleration is a vector quantity that includes both changes in speed and changes in direction.
Acceleration is the time rate of change of velocity. Velocity is a vector. It has a magnitude ( speed ) and a directio. If either the speed or the direction of motion changes the object is accelerating. Example; an object moving in a circle at constant speed is accelerating because its direction is continually changing.
To find the average speed of an accelerating object, you can calculate the average speed by taking the total distance traveled divided by the total time taken. However, note that the average speed may not accurately represent the motion of an accelerating object as it changes speed over time.
Some forces that do not cancel out or change an object's motion include net external forces, such as applied forces, frictional forces, and gravitational forces. These forces can cause changes in an object's motion, such as accelerating or decelerating it.
You would say that the object in motion is accelerating. Or you can say that the object's velocity is increasing.
When an object changes direction in its motion, its velocity changes, and if the object is accelerating, its acceleration will also change direction. This change in direction is due to the application of a force in the opposite direction. The object's kinetic energy may also change as a result of this change in direction.
The rate at which the speed or direction of its motion is changing.
Two-dimensional motion that is not always projectile motion would be circular motion, where an object moves in a circular path. Two-dimensional motion that is not projectile motion and does not accelerate the object could be uniform circular motion, where the speed is constant but the direction changes.
When an object is accelerating, its velocity is changing over time. This change in velocity can be due to an increase or decrease in speed, a change in direction, or both. The acceleration of an object is directly proportional to the force acting on it, as described by Newton's second law of motion.
