Instantaneous acceleration is the average acceleration between two points on the path in the limit that the time (and therefore the displacement) between the two points approaches zero. In calculus, instantaneous acceleration is the acceleration of an object at a specific moment in time. Δ t → 0, the average acceleration approaches instantaneous acceleration at time t0.

The acceleration at equals the slope of the line connecting the points (3.0 s, 4.0 m/s) and (4.0 s, 2.0 m/s).
The instantaneous acceleration, or simply acceleration, is defined as the limit of the average acceleration when the interval of time considered approaches 0.
In simpler words, the instantaneous acceleration is the acceleration carried by an object at a specific time. It is also defined in a similar manner as the derivative of velocity with respect to time. At time t the velocity is v → and at time t + ∆t it becomes v → + ∆v →. Find the instantaneous accelerations at , , and in figure (b).
Its the acceleration of an object at a particular instant/moment of time.
Average acceleration is the average of the accelerations acquired in the whole journey by a body while instantaneous acceleration is the acceleration of the body at any particular instant of time. Let δv is the change in velocity in an infinitely small interval of time δt, around t, then the instantaneous acceleration a t at the instant t is given by, When the acceleration that exists between two very close moments is discovered, the instantaneous acceleration is obtained. Acceleration is the change in an object's velocity divided.
The acceleration of the object at different instant of time or at given time of motion, is called instantaneous acceleration.
Instantaneous acceleration a(t) is a continuous function of time and gives the acceleration at any specific time during the motion. At this point, instantaneous acceleration is the slope of the tangent line, which is zero. When the object is moving with variable acceleration, then the object possesses different acceleration at different instant. Instantaneous acceleration, meanwhile, is the limit of the average acceleration over an infinitesimal interval of time.
∆v → / ∆t is the average acceleration of the particle in the interval ∆t.
The velocity change in instantaneous acceleration takes place at a specific time. It may be also defined as the limiting value of average acceleration over an interval of time, which approaches to zero. It’s the rate that the object changes it’s velocity. Instantaneous acceleration is the acceleration of an object at a specific moment of time.
It is calculated from the derivative of the velocity function.
In view (a), instantaneous acceleration is shown for the point on the velocity curve at maximum velocity. In simpler words, the instantaneous acceleration is the acceleration carried by an object at a specific time. The acceleration of the object at different instant of time or at given time of motion, is called instantaneous acceleration. When the object is moving with variable acceleration, then the object possesses different acceleration at different instant.
Its the rate of change of velocity w.r.t time.
We will use the general formula of average acceleration to find out the formula of instantaneous acceleration with the tweak of making the time elapsed nearly zero. It can also be explained as the velocity derivative with respect to time. Instantaneous acceleration is defined as the ratio of change in velocity during a given time interval such that the time interval goes to zero. Instantaneous acceleration is calculated as the average acceleration limit when a time interval attains zero.
It appears to be making step changes from one interval to the next, but in reality, there would be some line that connects each interval since it is really hard to have an instantaneous change in acceleration from one number to the next.
In the terms of calculus , instantaneous acceleration is the derivative of the velocity vector with respect to time: Instantaneous acceleration of a particle at time t is defined as a → = lim ∆t → 0 ∆v → / ∆t = dv → / dt where ∆v → is the change in velocity between the time t and t + ∆t. As an example, let’s say a car changes its velocity from one minute to the next—perhaps from 4 meters per second at t = 4 to 5 meters per second at t = 5, then you can say that the car is accelerating. Definition and formula for instantaneous acceleration the acceleration a that a particle has at an instant t is equal to the value that the average acceleration , calculated for an interval of time δ t which includes the instant t , approaches as the interval of time δ t gets smaller and smaller, i.e., as δ t approaches 0.

The acceleration of an object at any instant is called instantaneous acceleration. When the acceleration that exists between two very close moments is discovered, the instantaneous acceleration is obtained. Δ t = t 4 − t 3. But in average acceleration, it is over a period of time.
This acceleration can be measured when the average acceleration that occurs between two very short instants (as close as possible to 0).
