This Memorandum examines certain limitations, some practical considerations, and numerical examples in developing equations of motion for various vehicle propulsion systems. The main body of the study consists of four appendixes: (A) an analysis and summary of published information on vehicle resistance; (B) an analysis and summary of published information on the propulsion generated by various types of energy conversion systems; (C) acceleration-speed and time curves for various vehicle propulsion systems; and (D) equations of motion for the four phases of a typical trip: accelerating, deceleration, traveling at constant velocity, and remaining stationary.
This report is part of the RAND Corporation Research memorandum series. The Research Memorandum was a product of the RAND Corporation from 1948 to 1973 that represented working papers meant to report current results of RAND research to appropriate audiences.
This research in the public interest was supported by RAND, using discretionary funds made possible by the generosity of RAND's donors, the fees earned on client-funded research, and independent research and development (IR&D) funds provided by the Department of Defense.
Our mission to help improve policy and decisionmaking through research and analysis is enabled through our core values of quality and objectivity and our unwavering commitment to the highest level of integrity and ethical behavior. To help ensure our research and analysis are rigorous, objective, and nonpartisan, we subject our research publications to a robust and exacting quality-assurance process; avoid both the appearance and reality of financial and other conflicts of interest through staff training, project screening, and a policy of mandatory disclosure; and pursue transparency in our research engagements through our commitment to the open publication of our research findings and recommendations, disclosure of the source of funding of published research, and policies to ensure intellectual independence.
