What do you understand by the conservation of mechanical energy? State one condition under which mechanical energy is conserved. "Conservation of energy" refers to the fact that _____. If energy is conserved, t
This study explores the ontological perspective in analyzing students' problem-solving related to mechanical energy conservation. The research involves 18 high school students whose explanations were qualitatively analyzed using an extended ontological framework. Initially, students predominantly employed matter-...
Conservation of mechanical energy: The Law of conservation of mechanical energy states that in a closed-loop system, the kinetic energy may convert into potential energy, or potential energy may convert into kinetic energy in the absence of forces (like f...
Conservation of Mechanical Energy Homework Statement This is my first time posting here guys so correct me if I am wrong. This question was on my test and I wanted to know if I did it right. There is a block of mass m and it is moving at a certain velocity before pressing against ...
Conservation of Mechanical Energy: Equations not equivalent? 1. The problem A very simple question on a quiz given to me states that, "A 63 kg diver is standing on a diving board waiting to commence her dive. The diving board has compressed 0.08 m. Determine the elastic potential energy of...

英文: Using Newton mechanics method discussion about conservation condition of mechanical energy, we get the conservation under zero rotation and implict time in potential formula.中文: 摘要本文用牛顿力学方法分析了机械能守恒的条件,指出只有力满足旋度(方程式略)的条件,而且在势能的表达式中不显含时间,机械...
2.From the homogeneity of time we can deduce mechanical energy conservation law, and from the homogeneity and isotrogy of space we can deduce monentum conservation law andangular momentum conservationlaw.从时间的均匀性可推得机械能守恒定律 ,从空间的均匀性和空间的各向同性可分别推出动量守恒定律和角...
While −T:v→∘∇ represents a loss of mechanical energy, it produces internal energy within the volume V. If the flow is at rest v→=0, thus the balance of internal energy equation becomes: (2.97)∂∂t(ρε)+divq→=0 Substituting: (2.98)ε=cT and: (2.99)q→=−kgradT...
