Question

Which describes an object's velocity that changes by the same amount each second? constant acceleration constant time constant speed constant displacement

Answer 1

constant acceleration

because when the object's velocity is changing then the object is accelerating or decelerating
as acceleration describe changing of velocity so the answer is constant acceleration

Hope I can help u

Answer 2

Step-by-step explanation:

Acceleration is defined as the rate of change of velocity.

Acceleration = (Change in velocity) / time taken

Acceleration = (Final velocity - initial velocity) / time

As the object velocity changes by the same amount in each second, it means the acceleration is constant.
