it is just like gravitational effect on a rocket
it is the max vel required to overcome the circular motion tangential to the centripetal force

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 definition of vertical velocity?
Vertical means up and down; so the vertical velocity is an indication of how quickly an object is rising or falling. If the object is moving at an angle (such as an airplane taking off or landing) then it would be more accurate to call it the vertical component of the object's velocity.
When are velocity and acceleration perpendicular to each other?
When body is moving in a circle.
What is an object always changing if it is moving in a circle?
If an object is moving in a circle (like a teather ball or a planet in orbit, although orbit is not a perfect circle), then its velocity is always changing (remember that velocity is speed AND direction, and since the direction is changing, the velocity is changing). It's position is also always changing as a result of having a velocity.
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).

Can average velocity of moving body be zero?
Yes; for example, an object moving in a circle.
Can a body moving in a circle zero velocity and constant acceleration in circular motion have?
Nein. If it's moving, by definition it has non-zero velocity.
When are velocity and acceleration perpendicular to each other?
When body is moving in a circle.

Describe a situation in which the car has zero speed but has a definite acceleration?
An object moving at constant speed in a circle. Acceleration is rate of change of velocity, as velocity is speed in a certain direction, when moving in a circle an object's velocity is constantly changing, as its velocity is changing it is accelerating.
What is the motion of objects moving in two dimensions under the influence of gravity a. horizontal velocity b. directrix c. vertical velocity d. projectile motion?
horizontal velocity
How does motion in a vertical circle differ from that in a horizontal circle?
During motion in a vertical circle, the force of gravity (weight of the object) is in the same direction as the motion for half the time and in the opposite direction for the rest.For a body moving in a horizontal circle, gravity is acting orthogonally to the motion at all times.During motion in a vertical circle, the force of gravity (weight of the object) is in the same direction as the motion for half the time and in the opposite direction for the rest.For a body moving in a horizontal circle, gravity is acting orthogonally to the motion at all times.During motion in a vertical circle, the force of gravity (weight of the object) is in the same direction as the motion for half the time and in the opposite direction for the rest.For a body moving in a horizontal circle, gravity is acting orthogonally to the motion at all times.During motion in a vertical circle, the force of gravity (weight of the object) is in the same direction as the motion for half the time and in the opposite direction for the rest.For a body moving in a horizontal circle, gravity is acting orthogonally to the motion at all times.
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.
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
