例1如图1所示,有一倾角为θ的光滑斜面,一辆小车沿斜面滑下,车上有一单摆做微小摆动,摆长为l,求单摆的振动周期.解析设单摆随小车一起沿
Example 1 As shown in Fig. 1, there is a smooth slope with an inclination of θ. A small car slides down the slope. A single pendulum in the car makes a small swing. The pendulum length is l to find the oscillation cycle of the single pendulum. Along the car
