标题[题目] 能量转换
时间Sat Aug 25 13:08:23 2012
[领域] 牛顿力学
[来源] clasical dynamics of particles and systems
[题目] a particle is under the influence of a force F=-kx+kx^3/a^2,
where k and a are constants and k is positive.
1. Determine U(x) and discuss the motion .
2. What happens when E=(1/4)ka^2 ?
[瓶颈] 不清楚F与U(x)的关系
不知道如何转换
V(x)是否等於-x+x^3/a^2 微分?
感谢大大解答
