Question

Explain: a)positive acceleration b) negative acceleration c)zero acceleration. ​

Answer 1

Answer:

Hope it will help you

Explanation:

Positive acceleration: When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration.

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

Zero acceleration: Zero acceleration is an acceleration, just with zero magnitude. Motion with constant velocity is just a special case of motion with uniform (i.e. zero) acceleration.

Answer 2

Explanation:

a) when an object is speeding up the acceleration is in the same direction of velocity thus the acceleration is positive acceleration

b) is always refers acceleration in the direction opposite to direction of velocity. always reduce speed

c) is an acceleration just with zero magnitude. motion with a constant velocity in uniform
