Question

differential positive and negative acceleration ​

Answer 1

A positive acceleration means an increase in velocity with time. negative acceleration means the speed reduces with time. its a retardation. If the speed is increasing, the car has positive acceleration. When the car slows down, the speed decreases. When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration.

Answer 2

Answer:

Positive acceleration:

                 A positive acceleration means an increase in velocity with time. negative acceleration means the speed reduces with time. its a retardation. If the speed is increasing, the car has positive acceleration. When the car slows down, the speed decreases.

Negative acceleration:

               According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration
