One of the difficulties in studying mechanics is that many common words are used with highly specific technical meanings,among t
hem velocity, acceleration, position, speed, and displacement. The series of questions in this problem is designed to getyou to try to think of these quantities like a physicist.Answer the questions in this problem using words from the following list: A. position B. direction C. displacement D. coordinates E. velocity F. acceleration G. distance H. magnitude I. vector J. scalar K. components Part A Velocity differs from speed in that velocity indicates a particle's __________ of motion.Enter the letter from the list given in the problem introduction that best completes the sentence.
Part B Unlike speed, velocity is a __________ quantity.Enter the letter from the list given in the problem introduction that best completes the sentence.
Part C A vector has, by definition, both __________ and direction.Enter the letter from the list given in the problem introduction that best completes the sentence.
Part D Once you have selected a coordinate system, you can express a two-dimensional vector using a pair of quantities known collectively as __________.Enter the letter from the list given in the problem introduction that best completes the sentence. D Part E Speed differs from velocity in the same way that __________ differs from displacement.
