A spring has a spring constant of 50 N/m. How much force is required to stretch the spring by 2 m? A. 100 N B. 110 N C. 120 N D. 130 N 相关知识点: 试题来源: 解析 A。Force = Spring constant×displacement = 50×2 = 100 N. Option B, C and D are incorrect....
A spring has a spring constant of 50 N/m. How much force is needed to stretch the spring by 2 meters? A. 100 N B. 80 N C. 120 N D. 150 N 相关知识点: 试题来源: 解析 A。解析:Force = spring constant×displacement. 50 N/m×2 m = 100 N. Option B, C and D are ...
How much energy W needed to compress a spring from 15 cm to 10 cm if the constant of the spring is 150 N/m? If a spring has a constant of 20\ \matthrm{N/m}, how much potential energy does it store if it is compressed 2\ \mathrm{m} in ...

Hooke's law is valid for an object within its limit of elasticity. As per this law, the outer stress applied to an elastic object is directly proportional to the strain caused in it. The ratio of stress and strain is called the stiffness or sp...
A spring with a spring constant of 50 N/m is stretched by 0.5 m. What is the force exerted by the spring? A. 25 N B. 50 N C. 100 N D. 125 N 相关知识点: 试题来源: 解析 A。根据胡克定律 F = kx,其中 k 为弹簧常数,x 为伸长量。所以 F = 50 × 0.5 = 25 N。反馈 收藏 ...

在弹性系数(spring constant)k中,都有什么会影响弹簧的k值呢? 主要有三个因素: 材料、横截面积和原始长度, 其中原始长度越短,k值越大;横截面积越大,k值越大。K值是和整个弹簧的材料和形状都相关的。 在A-level数学的mechanics部分中,其实还有一个和弹性相关的物理量,叫做弹性模量(Elastic Modulus)λ。
