位移与加速度的相位相差180度,就像镜面对称一样。 ◆Definition of Simple Harmonic Motion: 简谐运动正式定义: A body is undergoing SHM when the acceleration on the body is proportional to its displacement, but acts in the opposite direction. 如果一个物体在外力作用下,其加速度与它的位移成正比例关系,...
And the same pendulum on the moon, where the force of gravity is 1/6th that of the gravity on the Earth, will also take longer to oscillate.We have glossed over one important aspect, in that this analysis is true only for small angles of theta. We had to make the approximation that...
Movement also helps kinesthetic learners understand concepts by providing a physical representation of the ideas they are trying to learn. For example, a kinesthetic learner will understand the concept of gravity better by acting out the force of gravity on their body. By engaging their bodies and ...
What is an expression for the time period of a simple pendulum? T = 2π√(l/g) l is the length of the pendulum. g is the acceleration due to gravity. Q3 On what factors does the energy of the particle executing S.H.M. depend? Mass of the particle. Square of the amplitude of...

For example, our belief in gravity affects our choice of actions and expectations. None of us would jump off a building because of the resulting crash landing that gravity would cause. When you sit in a chair, you are trusting gravity to hold you on the seat. And when you crack an egg...
In this tutorial, we won't cover physics engines. We will focus on the nonrealistic types of platformers. These can still emulate some effects from real life physics (for example, all platformers have some interpretation of gravity), but they're not structured to solve complex physical intera...

Reasoning up from first principles in investing is much more complex; as human-made concept, it strays from physics and mathematical laws (what is universally true- ie. gravity, Pi, etc.). Musk says that most people reason from analogy rather than first principles – this phenomena is especia...
