From conservation of energy to the principle of least action: A story line
نویسندگان
چکیده
We outline a story line that introduces Newtonian mechanics by employing conservation of energy to predict the motion of a particle in a one-dimensional potential. We show that incorporating constraints and constants of the motion into the energy expression allows us to analyze more complicated systems. A heuristic transition embeds kinetic and potential energy into the still more powerful principle of least action. © 2004 American Association of Physics Teachers. @DOI: 10.1119/1.1645282#

Enhancing Farmer Productive Capacity: Case of Action Research Based Conservation Agriculture
The study sought to explore approaches for co-creation of conservation agriculture (CA) knowledge amongst farmers, nongovernmental organizations (NGOs), government and specialist researchers. The aim of the study was to explore farmer initiated food security strategies among small holder resource poor farmers, through enhancement of farmers’ own productive capacity. The study was born out of th...
متن کاملEnergy Flows Modeling and Economic Evaluation of Watermelon Production in Fars Province of Iran
This study aimed to evaluate the efficiency of energy consumption and economic analysis of different watermelon cultivation systems in Fars Province of Iran. Watermelon production systems were classified into five systems, namely, custom tillage (group 1), conservation tillage (group 2), traditional planting (group3), semi mechanized planting (group 4), and mechanized planting (group 5).

متن کاملLeast Squares Analysis of Noise-Free Tides Using Energy Conservation and Relative Concentration of Periods Criteria
In this article, a new approach to tidal harmonic analysis is introduced. This approach incorporates more constituents in the least squares method for a fixed duration of noise-free tidal record and results in a more accurate tidal prediction. Moreover, it is demonstrated that 135 days of hourly data, which is significantly less than 369 days data in the Rayleigh criterion, is sufficient for th...
متن کاملAnalysis and Comparative of Grimas Actor Model in Pictures and Story of Sheikh Sanan
Attention to the narrative structure of stories from the twentieth century followed the science of linguistics and then semiotics as a branch of science. The narration of Sheikh Sanan is the most famous and longest story of Attar, which has been analyzed many times in terms of literature, narration and artistic since its creation. In the field of narration, Grimas proposed a comprehensive rule ...
متن کاملThe Analysis of the Discourse Markers in the Narratives Elicited from Persian-speaking Children
Discourse markers (DMs) are linguistic elements that index different relations and coherence between units of talk. Most research on the development of these forms has focused on conversations rather than narratives. This article examines age and medium effects on use of various discourse markers in pre-school children. Fifteen normal Iranian monolingual children, male and female, participated ...
