Question

What do you mean by zero, positive and negative acceleration

Answer 1

zero acceleration = the body is at rest , positive = body is in uniform motion in same direction , negative = when brakes are applied then its acceleration vector is directed in opposite side of its motion ; also known as retardation

Answer 2

@manasrokze zero acceleration doesn't mean that the body is at rest.

Answer 3

rather it means that the body's speed is constant during the motion.

Answer 4

also you're wrong with another interpretations. the positive acceleration would mean that the body's increasing its speed at a constant rate and that of the negative acceleration would mean that the body's decreasing its speed during the motion.

Answer 5

i have mentioned that positive acceleration means body is in uniform motion which is also equals to constant rate.... and in negative too mentioned the correct.... and 0 acceleration means that the body is neither in +ve acceleration nor in -ve which means it is in rest position.

Answer 6

so you're completely wrong! make sure you're already qualified before you're going to give help.

Answer 7

Your thought might be wrong..!

Answer 8

what do you mean by 'rest position'??????????

Answer 9

Rest position means initial velocity ( u ) = 0

Answer 10

the body is not involved in any type of motion

Answer 11

whatever you mean it is not held in the case of a zero acceleration.

Answer 12

a zero acceleration makes the body speeds at a constant rate
