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.
============================
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.

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.
Brakes are applied while the car is travelling north. Acceleration is toward the south, car slows down.

suppose when we apply brakes to a car in motion then the speed of the car decreases which means the acceleration is backwards but the car is still running in the forward direction
Acceleration
Freely falling body is a good example
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.
