Question

Explain position negative and zero acceleration
​

Answer 1

When the velocity of an object increases, the acceleration is positive.In this case, the acceleration is in the direction of Velocity. ... Its directions is opposite to the direction of Velocity. ⚫ Zero Acceleration. If the velocity of the object does not change with time,it has zero acceleration.

Answer 2

Explanation:

Negative acceleration means acceleration opposite to the direction of velocity ,it is also known as retardation (it always decreases the speed of the particle). ● Zero acceleration means body is not accelerating, in this case it's velocity is constant .
