Analytical cookies are used to understand how visitors interact with the website. c. The net force acting on the object is zero. copyright 2003-2023 Homework.Study.com. A. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object. In this limit, each acceleration vector becomes the instantaneous acceleration. Fill in the blank. Why average acceleration is equal to instantaneous acceleration? If you apply the same force to 2 objects, the one with more mass will have a greater acceleration. c. I. The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object.
