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 smoothly
without velocity being zero at some instant. A.True.

What is the magnitude of the velocity of a vertical projectile at its maximum height is equal to?
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
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.
How fast is a projectile moving at the top of its trajectory?
The vertical velocity is 0. The horizontal velocity is constant during the entire trajectory (and may be zero).
What is the vertical velocity of a projectile at the lowest point in trajectory?
It depends on the angle and speed at which it is fired.
How is the horizontal component of velocity for a projectile affected by the vertical component?
The horizontal component of velocity for a projectile is not affected by the vertical component at all. Horizontal component is measured as xcos(theta) Vertical component is measured as xsin(theta) Whereas theta is the angle, and x is the magnitude, or initial speed.

Projectile's vertical velocity component changes at a constant?
Gravity... I think
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.
Is the acceleration of a projectile equal to zero when it reaches the top of its trajectory?
No, assuming no air resistance, there will be a constant downward acceleration of 9.8 meters per second square (assuming standard gravity). The vertical component of the velocity will be zero at the top of the trajectory.
What is a vertical projectile?
One that goes directly up - the velocity having no horizontal component.
What is the name of the curved path of a projectile that accelerates only in the vertical direction while moving at a constant horizontal velocity?
rainbow trajectory
What is the value of the vertical speed at the highest point of the projectile's trajectory?
The value of the vertical speed at the highest point of the projectile's trajectory is the lowest speed at the maximum height reached.
How does the unbalanced force of gravity affect the horizontal and vertical velocity of an object in projectile?
In the absence of air resistance, the force of gravity has no effect on the horizontal component of a projectile's velocity, and causes the vertical component of its velocity to increase by 9.8 meters (32.2 feet) per second downward for every second of its flight.
