Question

what is negative acceleration ​

Answer 1

$\huge \bold \red {❥answer}$

Deceleration always refers to acceleration in the direction opposite to the direction of the velocity. Deceleration always reduces speed. Negative acceleration, however, is acceleration in the negative direction in the chosen coordinate system.

Answer 2

Answer:

When an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration.

Example:

(1) When we apply brakes in a moving car, then negative acceleration acts on it and the car stops.

(2) When we throw a ball upwards, then also negative acceleration acts on it.
