Hint: Acceleration is a vector quantity because it has both magnitude and direction. It is also the second derivative of position concerning time or the first derivative of velocity concerning time.
Complete answer:
According to Newton's second law, a body's acceleration is the sum of all the forces acting on it. Deceleration, also known as retardation or negative acceleration, is the acceleration that acts in the opposite direction of motion and is responsible for lowering a body's velocity.
Difference between acceleration and retardation:
Note: When an object moves in a straight line with an increase in velocity at equal intervals of time, it is said to be experiencing uniform acceleration. Uniform acceleration can be seen in the free fall of an object. If an object decreases its velocity by the same amount at equal intervals of time, it is said to be moving with uniform deceleration. It is also referred to as uniform retardation.

Difference between acceleration and retardation:
Acceleration | Retardation |
The rate of change of an object's velocity with respect to time is defined as acceleration. | The act or result of delaying; the extent to which something is retarded or delayed; that which retards or delays. |
The increase in velocity of an object per unit of time is referred to as acceleration. | Retardation is the inverse of acceleration and is defined as a decrease in velocity per unit of time. |
Acceleration can be positive (+), zero (0), or negative (-). | Retardation is the inverse of acceleration. Negative acceleration is also referred to as retardation or deceleration. |
For example, suppose an object was moving north at 10 meters per second. The object accelerates and is now moving north at a rate of 15 meters per second. The object has gained speed. | For example, when the brake is applied, the vehicle's velocity decreases. |
