百度试题 题目(翻译)Force F is a vector. The characteristics of a force are its magnitude, its direction, and its point of application 。相关知识点: 试题来源: 解析 正确答案:力F是一个矢量。力的三要素包括它的大小,方向和作用点 反馈 收藏 ...
力是束缚矢量是因为力需要考虑作用点，而自由向量是不需要考虑起点的！“力量是一种束缚的矢量”意思就是 “力量是一种克服另一种力做功”这样说应该明白了吧力是边界矢量

True or False: If a 100 N force is applied to lift an object with a mass of 10 kg, that object will be accelerated upward. Newton's Second Law of Motion: Of the three laws of motion postulated by Isaac Newton, the second is t...
Since force is a vector quantity, it is arguably impossible to directly probe the effect of force on a particular reaction because of heterogeneous application of force and a distribution of reaction orientations.427 To fully quantify the effect of an applied force on a chemical reaction, single...
void Start() { // Create a Force Field var go = new GameObject("ForceField", typeof(ParticleSystemForceField)); go.transform.position = new Vector3(0, 2, 0); go.transform.rotation = Quaternion.Euler(new Vector3(90.0f, 0.0f, 0.0f)); m_ForceField = go.GetComponent<ParticleSystemForce...

This chapter is concerned with force and torque actuators. Force actuators may be used by orbit and attitude control systems. To generate a torque, the force vector must not pass through the spacecraft center of mass. Typical force actuators are mass ejection devices (propulsion devices or thrust...
