Throwing a ball straight up in the air. It will reach some peak where the velocity is zero, but the acceleration due to gravity is a constant -9.8m/s^2.

Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.

Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.

As, in the velocity-time graph, curves passes through zero means 'when time is zero velocity is zero'. Velocity is time derivative of displacement. So displacement is maximum or minimum when time is zero in position-time graph.

If your velocity is constant, then your acceleration is zero.

Yes. For example a swinging pendulum has zero velocity at the turning point but acceleration is not zero.

Yes, an object moving at a constant velocity has zero acceleration even though it has a non-zero velocity. For example, a car driving at a steady speed on a straight highway has a constant velocity but zero acceleration.

An object at rest has zero momentum. For example, a stationary rock on the ground has zero momentum because both its mass and velocity are zero.

Yes, the average velocity of a moving body can be zero. For example, if an object moves to the right for a certain distance and then returns back to its original position in the same amount of time, the total displacement would be zero, resulting in an average velocity of zero.

Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.

Not necessarily. If the net force acting on a body is zero, the body's velocity will remain constant (assuming no other forces act on it to change its velocity), but it doesn't mean the velocity will be zero. If the initial velocity is zero, then the velocity will remain zero if the net force is zero.

The momentum of an object with zero velocity is zero. Momentum is calculated as mass multiplied by velocity, so if velocity is zero, momentum will also be zero.

For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.

Yes, an object with zero velocity can have an acceleration that is greater than zero if there is a change in its velocity over time. Acceleration is the rate of change of velocity, so even if the object starts with zero velocity, it can still accelerate if its velocity increases or decreases.

Yes, it is possible for the initial velocity to be different from zero when the final velocity is zero. For example, an object could be thrown upwards and come to a stop at its highest point, where the final velocity would be zero.

Velocity at zero means the object is not moving, while acceleration at zero means the object is moving at a constant velocity. Velocity at zero can be motionless or stationary, while acceleration at zero indicates that there is no change in velocity, even if the object is moving.

An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
