The energy of a particle or system of particles derived from position, or condition, rather than motion. A raised weight, coiled spring, or charged battery has potential energy.
粒子或粒子系统因其位置或状态而非运动而具有的能量。举起的重物、压紧的弹簧或充了电的电池都具有势能。
The change in the momentum of a system of particles during an impact is equal to the vector sum of all the external impulses acting on the system.
碰撞时质点系动量的改变等于作用在质点系上所有外碰撞冲量的矢量和。
This paper proposes the theorem of moment about mass acceleration of the particle and the system of particles (absolute motion and relative motion).
本文提出质点和质点系(绝对运动和相对运动)质量加速度矩定理。
This paper aimed to achieve the dynamics model of mass terms for PMAs. In the modeling, PMAs were considered as a system of particles which were distributed uniformly along a cylinder.
单独考虑气动肌肉的质量项并在动力学推导中将其看成沿圆柱体均匀分布的质点系，利用拉格朗日方程建立了气动肌肉质量项动力学模型。
