Think of any five different things (car, train, runner, fly, bird) slowing down as they continue traveling forwards. The direction of motion is shown by the velocity vector. The acceleration in each case is in the opposite direction.
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.
Acceleration can be in the opposite direction of motion, which is called deceleration. Acceleration can also be in the same direction as motion, causing an increase in speed. The direction of acceleration depends on the forces acting on the object.

If an object is moving to the right with a velocity vector of 5 m/s, and then a force is applied to the left causing the object to slow down, it experiences acceleration against the direction of motion. This acceleration would act in the left direction, opposing the object's initial motion to the right.
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 a car is moving forward and the driver suddenly applies the brakes to stop, the car's acceleration is against the direction of motion. This is because the acceleration due to braking acts in the opposite direction of the car's velocity, causing it to slow down.
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).
Throwing an object straight up in the air is an example of a motion in which acceleration is in the direction of motion. After the object is released, the acceleration due to gravity acts downward, which is in the same direction as the motion of the object as it goes up and then comes back down.
The direction of the centripetal acceleration vector in circular motion is towards the center of the circle.
The direction of acceleration affects the direction of motion by causing a change in velocity. If the acceleration is in the same direction as the velocity, the speed of the object increases. If the acceleration is opposite to the velocity, the speed decreases, and if the acceleration is perpendicular to the velocity, the object changes direction without changing speed.
No, the acceleration of an object is in the direction of the net force applied to it. If the net force is in the same direction as the object's motion, the acceleration will be in the same direction. If the net force is opposite to the object's motion, the acceleration will be in the opposite direction.
If an object is moving in one direction and slows down, then the direction of its acceleration is opposite to the direction of its motion. This occurs because the acceleration is acting in the direction to oppose the motion and eventually bring the object to a stop.
