A. Newton's First Law B. Newton's Second Law C. Newton's Third Law D. None of the above 相关知识点: 试题来源: 解析 B。<解析:公式F = ma表达的是力、质量和加速度之间的关系,这正是牛顿第二定律的内容,所以答案为B。A选项牛顿第一定律主要是关于惯性的;C选项第三定律是作用力与反作用力的关...
A. It has nothing to do with them. B. It contradicts the first two laws. C. It complements the first two laws by explaining the nature of forces in interactions between objects. D. It is the same as the first two laws. 相关知识点: 试题...
Newton's third law states that for every action, there is an equal and opposite reaction. During the collision between X and Y, the force exerted by X on Y is equal in magnitude but opposite in direction to the force exerted by Y on X. Since the time interval of the collision is the...
Newton's second law of motion describes force.It says:force equals the mass of an object,multiplied by the change in speed it produces in an object. 相关知识点: 试题来源: 解析 牛顿第二运动定律描述了作用力:力等于是物体的质量乘以该物体速度的变化率.(即F=ma,速度的变化率就是加速度) ...

9 Which of the following is Newton's Third Law? A A For every action there is an equal and opposite reaction. B What goes up must come down. C The acceleration that a resultant force produces depends on the size of the force and mass of the object. D An object will continue to ...
Newton's laws of motion pl n (General Physics) three laws of mechanics describing the motion of a body.The first lawstates that a body remains at rest or in uniform motion in a straight line unless acted upon by a force.The second lawstates that a body's rate of change of momentum ...
Newton's First Law, also known as the law of inertia, is a fundamental principle in physics. It states that an object at rest will remain at rest and an object in motion will continue in motion with a constant velocity in a straight line unless acted upon by an external force. Isaac ...
