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.
The velocity at the highest point of motion is zero, so the change in velocity from 1 second before to 1 second after is the final velocity after the highest point minus the initial velocity before the highest point. Since velocities at these points have opposite signs, the magnitude of the change in velocity would be the sum of the speeds at the corresponding points.
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.
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.
At the highest point of a ball's vertical motion, its velocity is zero. This is because the ball briefly comes to a stop before falling back down due to gravity.
The ball has an instantaneous velocity of zero at the highest point of its trajectory. This is because at that point, the ball changes direction from going up to coming down, causing its velocity to momentarily be zero before increasing in the opposite direction.

At the highest point in its trajectory, the vertical velocity of a projectile is zero. This is because the projectile has reached its peak height and is momentarily at rest before starting to descend.
At the highest point, the velocity of an object thrown vertically into the air is momentarily zero as it changes direction. This is the point where it transitions from going upward to downward.
At the highest point of oscillation, the velocity of an object is zero because it has momentarily stopped moving in the vertical direction and is changing its direction of motion from upwards to downwards due to the force of gravity acting on it. This point is where all the kinetic energy has been converted into potential energy and vice versa.
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.
At the highest point of its trajectory, the direction of an oblique projectile will be horizontal. This means that the projectile will momentarily have zero vertical velocity and only horizontal velocity.
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.
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.
