Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion.
Example : A car accelerating at 1m/s2 uniformly in a straight line.
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.
If the average acceleration is zero, it means that the object's velocity is not changing over time. Since instantaneous acceleration is the acceleration at a specific moment in time, it can still have a non-zero value depending on the instantaneous velocity of the object at that moment.
Instantaneous acceleration and average acceleration are the same when an object's acceleration is constant over the entire time interval being considered. This means that the object's velocity is changing at a constant rate, resulting in both the instantaneous and average accelerations being equal.
average acceleration is the average of the acceleration of a body in its entire motion where as instantaneous acceleration is the rate of change of velocity at an instant. it may be a function of time or velocity or displacement.
The instantaneous average acceleration vector is given by the derivative of the velocity vector with respect to time. Mathematically, it can be written as ( \overrightarrow{a}(t) = \lim_{{\delta t \to 0}} \frac{{\overrightarrow{v}(t + \delta t) - \overrightarrow{v}(t)}}{{\delta t}} ), where ( \overrightarrow{a}(t) ) is the acceleration vector at time ( t ) and ( \overrightarrow{v}(t) ) is the velocity vector at time ( t ).

When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
you are still. motion is at rest.
Suppose you accelerate in your car from stopped to 50 km.hr-1. When you were stopped your instantaneous speed was zero. At the end of the period of acceleration your instantaneous speed was 50 km.hr-1. If your rate of acceleration was constant then your average speed was 25 km.hr-1.
The instantaneous average acceleration vector is given by the derivative of the velocity vector with respect to time. Mathematically, it can be written as ( \overrightarrow{a}(t) = \lim_{{\delta t \to 0}} \frac{{\overrightarrow{v}(t + \delta t) - \overrightarrow{v}(t)}}{{\delta t}} ), where ( \overrightarrow{a}(t) ) is the acceleration vector at time ( t ) and ( \overrightarrow{v}(t) ) is the velocity vector at time ( t ).
Dividing change of velocity by the time it takes to change the velocity. If acceleration is not constant, this will give you the average acceleration during the period; to get the instantaneous acceleration, you have to take the derivative of the velocity.
You can't tell from the information given. All you know is that the average acceleration is (change in speed) divided by (time for the change) = (6/8) = 0.75 meters per second2. The force required depends on the mass of the object to be accelerated by the force.
When the average velocity of a body is equal to its instantaneous velocity, it means that the body is moving at a constant speed in a straight line. This indicates that the body's motion is uniform, with no acceleration or deceleration occurring.
The average acceleration can be obtained by finding the slope of the graph. The instantaneous acceleration is found by drawing a tangent to a particular point on the graph (instant) and finding the slope of than tangent.
