That being said, there are natural ways to come up with the idea of even considering that force is a vector. Specifically, each force has a direction and a magnitude. As pointed out in other comments, this doesnt necessarily mean that is must be a vector (kinetic energy clearly has a di...
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 ...
解析 = 36 The displacement vector is D= (PQ)=2,5,2, so by Equation 12, the work done is(split) W&= F⋅ D=3,4,5⋅ 2,5,2\&=6+20+10=36(split)If the unit of length is meters and the magnitude of the force is measured in newtons, then the work done is 36 J....

a. A vector quantity that tends to produce an acceleration of a body in the direction of its application. Newton's second law of motion states that a free body accelerates in the direction of the applied force and that its acceleration is directly proportional to the force and inversely propo...
百度试题 结果1 题目请问什么是bound vector.原句为这样:force is a bound vector 相关知识点: 试题来源: 解析 “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反馈 收藏

(9.6). If the problem is of two dimensions, namely, all the forces lie in the Oxy plane, only the first two columns of F and R need to be specified. resultant (F) only computes the resultant force. [F_sum, M_sum] = resultant (F, R) returns the resultant force in a vector F...
What would the universe be like if we would give up theprinciple of equivalenceand as a consequence incorporate gravity on a more traditional interaction basis within the theory of special relativity? The current work proposes such a gravitational model where a new law of gravitation is expressed ...
