In summary, acceleration is the rate of change of velocity with respect to time. Instantaneous acceleration determines how instantaneous velocity changes in an infinitesmall amount of time, while average acceleration correlates to the velocities of a time interval. To find instantaneous acceleration, we need to know the instantaneous velocity for every t inside the time interval. Similarly for velocity, we need to know the instantaneous location for every t inside an interval. At any instant, the instantaneous velocity can be defined as v(t).

But to find the instantaneous acceleration we need to know the instanteneous velocity v(t) for every t inside (t1,t2) and not just only the two velocities v2 and v1 at the edges of the time interval t2 and t1. If we know v(t) then the instantaneous acceleration is [tex]a(t)=\frac{dv(t)}{dt}[/tex].

So, at any instant, can the instantaneous velocity be defined, or is it changing? ()

Can be defined and its value at any instant t is v(t)

Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity, meaning it has both magnitude (speed) and direction.

Instantaneous velocity is the velocity of an object at a specific moment in time. It is the slope of the tangent line to the object's position-time graph at that point.

Acceleration and instantaneous velocity are related in that acceleration is the change in instantaneous velocity over time. In other words, acceleration is the rate at which an object's velocity is changing at a given moment in time.

Yes, there is a correlation between acceleration and instantaneous velocity. As acceleration increases, the change in instantaneous velocity also increases. This means that if an object is accelerating, its instantaneous velocity is changing at a faster rate.

Acceleration can be calculated by dividing the change in velocity by the change in time. Instantaneous velocity can be calculated by finding the slope of the tangent line to the object's position-time graph at a specific point. Both can also be calculated using calculus equations, such as derivatives and integrals.
