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.

What is its velocity at the highest point of a ball vertically upwards?
In that case, the velocity is zero.
In projectile motion Why is the vertical component of velocity zero at the highest point of the trajectory?
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.
Why at the highest point is the change in velocity zero?
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.
A ball is thrown with enough speed straight up so that it is in the air several seconds What is the velocity of the ball when it gets to its highest point?
A the highest point its velocity will be zero.
When a ball is thrown up what is its acceleration and velocity at the highest point?
0 zero

0 zero
Can a body have acceleration with zero 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.
What is the vertical velocity of a projectile at the highest point in its trajectory?
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.
What is the momentum at the highest point of a ball thrown vertically upwards?
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.
What hasa zero velocity yet a non-zero acceleration?
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.
When an object At the highest point there's an instant when the motion is changing from upward to downward then what is its velocity?
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.
Can velocity be zero and acceleration not?
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.
A ball is thrown straight up At the top of its path its instantaneous speed is?
If it is thrown at an angle, at the top of its path, its vertical velocity will be zero, however its horizontal velocity will be the same as its initial horizontal velocity minus whatever loss in speed as a result of air friction at that point. We won't know what that is without more information.
