If the average velocity of an object is zero in some time interval, what can you say about the displacement of the object for that interval
Answer to relevant QuestionsCan the instantaneous velocity of an object at an instant of time ever be greater in magnitude than the average velocity over a time interval containing the instant? Can it ever be less?Two cars are moving in the same direction in parallel lanes along a highway. At some instant, the velocity of car A exceeds the velocity of car B. Does this mean that the acceleration of A is greater than that of B? Explain.The electrons of atoms are arranged in three-dimensional energy-level “shells” or spheres.
