Can an object have zero velocity and non zero acceleration at the same time?

Yes. Consider a skydiver in freefall. Fairly quickly the skydiver will reach terminal velocity (the speed at which their acceleration from gravity is cancelled out by the resistance of the air through which they are falling).
At terminal velocity the skydiver has non-zero velocity (about 56m/s or 200km/h) but zero acceleration (because their velocity is not increasing).
In a vacuum, where there is no air resistance, there is also no terminal velocity. Because there is no force acting against acceleration an object will continue to accelerate provided its source of acceleration continues to be applied. It is worth noting that an object cannot use this rule to exceed the speed of light because as the speed of light is approached the relative time for the object slows.
On earth, however, or indeed in any similar environment, an object can certainly have zero acceleration and non-zero velocity.

∙ 7y agoWhen a body is thrown vertically upward, for a moment on the top most position it stops and then it again comes back. At that particular point its velocity and speed becomes zero but acceleration due to gravity is still acting on it .

in a straight line indicates zero acceleration.

When the acceleration of an object is zero what is the velocity at the same time?
As long as acceleration is zero, the object's velocity is constant.
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
When does an object's acceleration change?
Acceleration is change of velocity / time.
Which describes an object's velocity that changes by the same amount each second?
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
What is the difference between Velocity and Acceleration of an object?
Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.
When does a force change the velocity of an object?
If the object is in free-space, and any force applied over a period of time will change the velocity of an object. Force = mass * acceleration. Acceleration = velocity / time. Therefore, Force = mass * velocity/time.
If an object is accelerating what equation relates the acceleration of that object the initial velocity and the final velocity and time?
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
How do you calculate an objects acceleration?
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
Acceleration is the rate at which happens?
acceleration is the rate of change of velocity with respect to time.
What is the formula in finding the acceleration of an object?
acceleration = change in velocity / time
Can an object be accelerating if it has constant velocity?
No. The definition of acceleration is the change in an object's velocity over time. Acceleration must then be zero since velocity remains constant.
What is the meaning if acceleration?
acceleration is the rate of change of velocity of an object with respect to time.
