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.

Why is the velocity zero at highest oscillation point?
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 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.
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.
When an object and acceleration is zero at some instant t in time its velocity is?
You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.
The rate at which velocity is changing at a given instant is described by?
The answer is: Instantaneous Acceleration.

How fast velocity is changing at a specific instant?
Acceleration is the rate of change of velocity.
When an object and acceleration is zero at some instant t in time its velocity is?
You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.
Acceleration is how fast a velocity is changing at a specific instant?
Yes, plus the direction that it's changing in.
The rate at which velocity is changing at a given instant is described by?
The answer is: Instantaneous Acceleration.
Is it possible for a body with zero velocity to have non-zero acceleration?
Yes, but only for a single instant in time. When you throw a golf ball or a rock straight up, it has the constant downward acceleration of gravity from the moment it leaves your hand, but its velocity is certainly not constant. The velocity steadily decreases until the peak of the toss, and then it switches from upward to downward velocity. At the very peak, the velocity is zero for an instant.
Is how fast velocity is changing at a specific instant?
That's the magnitude of instantaneous acceleration.
What is the skydiver's downward velocity at that instant just before starting to fall?
The same as that of the aircraft that he /she is in. If flying level, it would be zero.
What is acceleration at instantaneous maximum velocity?
In the case of an object thrown, batted, teed off, or dropped, its acceleration at the instant of its maximum velocity is 9.8 meters per second2 downward.
What is how fast a velocity is changing at a specific instant?
IF it changes to the completely opposite direction ... does a 180 or a "U-turn" ...then the velocity must be zero at that instant. But if the direction only changesby turning a corner or going around a bend, then there's no way to know whatthe velocity is without a lot more information.
