功的计算公式W=Fs只适合计算恒力的功,对变力做功不适用。如何求变力的功呢?1.图像法某物体受一变力F的作用,F随时间变化的规律为F=F
The formula for calculating work W = Fs is only suitable for calculating the work of constant force, but not for the work of variable force. How to seek the power of change it? 1. Image Law by a variable force F role, F with the law of time F = F
