That's the magnitude of instantaneous acceleration.
The rate of change of velocity is known as acceleration. This can come in different forms (linear / nonlinear acceleration, angular acceleration ect).
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.
Assuming that there is no velocity in the horizontal direction, then the velocity at that instant is zero.
Its velocity
a=dv/dt=d/dt(dx/dt)=d^2x/dt^2Is the rate of a tangent to the slope of a graph signifying velocity versus time. It is a snapshot of acceleration at a precise moment in time based on the relative changes in velocity over time. It is the limit of acceleration for any given point within the displacement vector.Instantaneous acceleration is how fast a velocity is changing at a specific instant.
Acceleration is the rate of change of velocity.
Yes, plus the direction that it's changing in.

the answer is velocity
Since velocity is speed with direction, you would use speed in reference to average rate of change of position, since the direction keeps changing. You can use velocity in reference to instantaneous speed, since a car is going in a specific direction at each instant in time.Examples:80 km/h is a speed.80 km/h due north is a velocity.
Velocity . . . what speed and direction something is moving. Acceleration . . . how fast the speed and/or direction of its motion are changing.
This is known as acceleration (rate of change of velocity) measured in units of m/s/s or m/s2
The rate of which something changes its velocity is the acceleration. A common mistake is to think that something moving fast is accelerating, but it's only accelerating if the velocity of that object is changing.
