When two equal and opposite forces act on an object, the object is said to be in a state of ___. A. motion. B. acceleration. C. equilibrium. D. deformation. 相关知识点: 试题来源: 解析 C。原因:当两个大小相等方向相反的力作用在物体上时,物体处于平衡状态。A 选项运动不符合这种情况;B...
英语翻译NEWTON Ⅲ:EQUAL AND OPPOSITE(作用力与反作用力)All objects,moving or at rest,obey Newton’s third law of motion,which holds that in nature,unaccompanied(无陪伴的) forces do not exist. 答案 牛顿第三定律:作用力与反作用力一切运动或静止的物体,都遵循牛顿第三定律,不存在单一的力使其维持运动...
When equal and opposite forces applied to a body 10 to along it it the stress so produced is called? Answer: When an equal and opposite force is applied to a rigid though merely elastic body, the stress produced is considered and known to be 'tensile stress'. When two equal opposite and...
A cube of incompressible neo-Hookean material undergoes a pure homogeneous deformation and is held in equilibrium by three specified pairs of equal and opposite forces, two of which are the same, applied normally to its faces and uniformly distributed over them. The possible equilibrium states are...
Step 5: Analyze the ForcesAs discussed, the forces acting on both blocks are equal in magnitude and opposite in direction:F1=kxandF2=−kxThus, the forces are equal and opposite, confirming that option C is correct. Step 6: Analyze the Linear MomentumFrom the conservation of momentum, we ...
14 A ruler of length 0.30m is pivoted at its centre. Equal and opposite forces of magnitude 2.0N are applied to the ends of the ruler, creating a couple as shown.2.0N一50°ruler pivot50°2.0N What is the magnitude of the torque of the couple on the ruler when it is in the positio...

Does an unbalanced force need to act upon an object, for the object to move, even though there are equal and opposite forces acting upon the object? If you double the force on an object but the distance remains the same, how much work is done on t...
Newton's third law states that for every action done in this universe, there is equal and opposite reaction. Famous example is rocket which shoots upwards due to the thrust of hot gases coming out of rear. Key Ideas:A mass at rest on a ...
aWhenever two bodies interact they apply forces of equal size but opposite direction on each other. Every action has an equal and opposite reaction. 每当二个身体交互式他们在彼此应用相等的大小力量,但在方向对面。 每次行动有相等和相反反应。 [translate] ...
