Answer 2

Answer:

 WHEN YOUR CAR IS SPEEDING UP AND CHANGING TO HIGHER GEARS,

YOUR CAR IS SAID TO BE ACCELERATING, THIS CAN PICK YOU TO THE

MAX. SPEED OF THE CAR (SUPPOSE 160 KM/HR)

  WHEN YOUR CAR IS REDUCING THE SPEED AND FALLING TO LOWER GEAR, YOUR CAR IS SAID TO BE DECELERATING, THIS HELPS YOU TO

STOP AT A PARTICULAR DESTINY.

SO,  WHEN CAR IS SHIFTED FROM LOWER TO HIGHER VELOCITY,

ACCELERATION IS POSITIVE.

WHEN YOUR CAR IS REDUCED FROM HIGHER TO LOWER VELOCITY,

ACCELERATION IS NEGATIVE.
