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.
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
Instantaneous speed is the speed of an object at a specific moment in time, while speed refers to the average rate at which an object covers distance over a period of time. Instantaneous speed gives the speed at a precise instant, whereas speed provides an overall measure of how fast an object is moving.
That's correct, the instantaneous magnitudes are equal. Non-instantaneous values may not be equal. For example, to find average speed, between two points, you divide the actual path distance by the time, but for average velocity you divide the straight line distance, between the points, by the time. The straight line distance could be quite a bit shorter then the actual path distance (for curved motion) so you could get a big difference between those averages. When calculating "instantaneous" values, however, the difference between "actual path distance" and "straight line distance" becomes insignificant, because you are using distances for infintesimally small time intervals.
It means acceleration at a specific instant of time. You can calculate the average acceleration by dividing change of velocity, by the time during which this changes. If you take smaller and smaller times, dividing change of velocity by a small time interval in every case, you can imagine approaching the "true" acceleration.
Instantaneous speed:- It is the rate of change of position with respect to time,at that instant. Average speed:-Average speed is defined as the total path length travelled divided by the total time interval.
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.
Instantaneous speed is the speed at a particular moment in time.The average speed of an object tells you the (average) rate at which it covers distance
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
Average or instantaneous? The average is the height divided by the horizontal distance, whereas the instantaneous alternates between zero and infinity.
Depends. Slope of tangent = instantaneous rate of change. Slope of secant = average rate of change.
The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.
Instantaneous speed is the speed of an object at a specific moment in time, while speed refers to the average rate at which an object covers distance over a period of time. Instantaneous speed gives the speed at a precise instant, whereas speed provides an overall measure of how fast an object is moving.
Gravitational acceleration is simply acceleration due to gravity.
That's correct, the instantaneous magnitudes are equal. Non-instantaneous values may not be equal. For example, to find average speed, between two points, you divide the actual path distance by the time, but for average velocity you divide the straight line distance, between the points, by the time. The straight line distance could be quite a bit shorter then the actual path distance (for curved motion) so you could get a big difference between those averages.

average velocity is the displacement over time while instantaneous velocity refers to the velocity of an object at one point or at as pecific point of time. *displacement is the difference between the initial position and the final position of an object. (distance 2 - distance 1)
