根据单摆周期公式,周期与摆长有关,与摆球的质量、摆动幅度和初始摆动速度基本无关。The mass of the pendulum bob表示摆球质量,不影响周期;The amplitude of the swing表示摆动幅度,在小角度摆动时对周期影响极小;The initial velocity of the swing表示初始摆动速度,也不是影响周期的主要因素。

A simple pendulum is a type of mental construct or idealized theoretical model in which a point sized mass is suspended from a...
Here are some drills to learn how to use it inside a boxing ring once you understand the bounce:1) Heavy Bag DrillStart the drill by pushing the bag away from you and start your pendulum motion, in tune with the bag’s movement. Try to get as close as you can to the bag without ...
It was a superstition, but a superstition of such a class, that he who knows the story and has seen this picture, need have only two words placed under the picture to make him understand it; and these two words are: “A mother.” Twenty-Fifth Evening IT was yesterday, in the morning...
What do you understand by action and reaction forces? Because of deformation, what can kinetic energy be converted into? What is the Physics behind balancing of a Bicycle? Explain. Does the static friction between two surfaces change with their size? Explain. ...
Recommendation: The Department should set out a plan by December 2017 for how it will fill gaps in its knowledge about the school estate in areas not covered by the property data survey. Specifically it needs to understand the prevalence, condition and management of asbestos, and know more abou...

I can think of one more way to figure out what we can't say: to look at how taboos are created. How do moral fashions arise, and why are they adopted? If we can understand this mechanism, we may be able to see it at work in our own time. ...
