All those physics books saying them different are wrong. I think that the difference in the gravitational field and the gravitational acceleration comes directly from their definition.
It is assumed that first a body creates a gravitational field around itself and then this field exerts a force on another body. Sign up to join this community. The best answers are voted up and rise to the top.

Edit Comment As a couple of answers point out, physically, the two quantities are different as the former the field intensity is the quantity that describes the physical entity that the gravitational field is at a certain point whereas the latter the acceleration due to gravity describes the acceleration a characteristic of the motion of the particle put in the field.
Improve this question. Dvij D. Add a comment. Active Oldest Votes. Improve this answer. Farcher Farcher Please clarify your definitions of "gravitational intensity" and "gravitational acceleration". With the definitions I'd go with g-field as the sum of all fields produced by all point masses the statement "it does not imply that the gravitational acceleration of any [point] mass at that point is equal to E" is false.

Recall from an earlier lesson that acceleration is the rate at which an object changes its velocity. It is the ratio of velocity change to time between any two points in an object's path.
To accelerate at 9. If the velocity and time for a free-falling object being dropped from a position of rest were tabulated, then one would note the following pattern.
Observe that the velocity-time data above reveal that the object's velocity is changing by 9. That is, the free-falling object has an acceleration of approximately 9.
Another way to represent this acceleration of 9. The velocity of the ball is seen to increase as depicted in the diagram at the right. NOTE: The diagram is not drawn to scale - in two seconds, the object would drop considerably further than the distance from shoulder to toes. Physics Tutorial. My Cart Subscription Selection.
