free fall motion国际化是当今世界教育的一个重要特征和趋势.教育国际化就是用国际视野来把握和发展教育.在基础教育中,越来越多的一线教师在备课时除了认真研读国内教材外,还会参考一些国外流行的高中课本,从而借鉴国外课本的精华.笔者在国内外课本的对照中,发现有一些概念的理解容易出现偏差.比如说:自由落体运动和...
Free fall equation If you want to calculate the distance traveled by a falling object, you need to write down the equation of motion. If the initial displacement and velocity are both equal to zero, it boils down to: s=12gt2s=21gt2 If the object is already traveling with an initial vel...
In a uniformly accelerated motion, the acceleration of the moving object remains constant. Also, the velocity-time graph is a straight line with some slope. To understand a uniformly accelerated motion, we use the 3 Kinematics equations of motion. These equations relate to the ...
Einstein’s theory of gravity—the general theory of relativity1—is based on the universality of free fall, which specifies that all objects accelerate identically in an external gravitational field. In contrast to almost all alternative theories of gravity2, the strong equivalence principle of gener...

Free Fall Motion is simple mechanical system of a single object with mass, m, falling freely to the ground under the force of gravity. To calculate the Hamiltonian of the free fall motion system, we can express the object's kinetic energy, T, and potential energy, V, as: T...
Can we use Lagrange Equation to solve the problem of Free Fall Motion? The answer is of course. Consider an object with mass m in free fall motion (source: owlcation.com): Object in Free Fall Motion The object's kinetic energy, T, and potential energy, V, can be expressed as below,...
Kinematic equations relate the variables of motion to one another. Each equation contains four variables. The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are
