moving forward continuesly
An example of acceleration in the direction of motion is a smooth spherical stone dropped from the roof of a building on a windless day. All the motion is straight down, toward the center of the earth, and so is the acceleration.
deceleration in a linear motion (braking during driving or an object thrown up while you are standing on on earth) --> the acceleration is pointing at an opposite direction than the motion. ============================
A change in velocity
Because 'acceleration' does NOT mean 'speeding up'. It means any changein speed or direction of motion.Uniform circular motion involves constantly changing direction, and that'sconstant acceleration.
When acceleration is opposite to (against) the direction of motion, the magnitude of the velocity decreases, meaning that the object slows down. An example is the application of the brakes to slow or stop a car. During the time that the pressure remains on the brake pedal, the car's acceleration is negative ... meaning opposite to the direction of motion ... and the car's speed is decreasing.

Freely falling body is a good example

Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
Acceleration in motion refers to a change in speed or direction of that object's motion. So a type of motion in which speed and direction do not change is a motion in which the acceleration is constant (i.e. unchanging).
'Acceleration' is a change in the speed and/or direction of motion.
