Note - the vertical velocity is zero ... there may be considerable horizontal velocity.
And vertical velocity is zero because the object is going neither up nor down.
Just before it reaches the highest point, the vertical component of velocity is upward.Just after it passes the highest point, the vertical component of velocity is downward.There's no way you can change from an upward velocity to a downward velocity smoothlywithout velocity being zero at some instant. A.True.
At the highest point, there's an instant when the motion is changing from upward to downward. At that exact instant, the speed is zero, and that's zero velocity.
In that case, the velocity is zero.
A the highest point its velocity will be zero.
0 zero

Yes, but only for an instant. For example, if you throw a stone up, when it is at its highest point it has a velocity of zero, but its acceleration is -9.8 m/s2. If there is acceleration, the velocity can not remain at zero.
The vertical velocity is zero at the highest point. It has ceased moving upward and will begin moving downward. Gravity and air resistance will have negated the original vertical velocity (y-component). So the velocity at the highest point has only a horizontal or x-component.
The highest point is the point where the ball's velocity transitions from upward to downward. At that instant, the ball's speed, velocity, momentum, and kinetic energy are all exactly zero.
Answer:Yes, but only instantaneously.Consider a thrown ball moving directly upward. At the highest point of its trajectory, the instanataneous velocity (the velocity at that precise instant) is zero even while the acceleration due to gravity remains non 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.
At that moment, its vertical velocity is zero. Its horizontal velocity may or may not be zero, i.e., it may be moving sideways as well.
Yes. If you throw an object up, the moment it is at its highest point, the velocity at that instant will be zero, whereas the acceleration is -9.8 meters per second square. In other words, the velocity won't remain zero for a long time.
