This is my review of  Unit 1: Kinematics, for AP Physics 1.

这是我对 AP 物理 1 的第一单元：运动学的复习。

Maximum stability is guaranteed by the strong kinematics and solid leader design.

强大的运动学和坚固的导保证了最大的稳定性。

So, the definition of acceleration is the first of the two main kinematic equations that we’ll be using. But it only links velocity, acceleration, and time. What about position?

因此，加速度的定义是我们将要使用的两个主要运动学方程中的第一个。但它链接速度、加速度和时间。 位置呢？

They collected data on plantar pressure, joint kinematics and muscle parameters during running and resistance exercises under different load conditions, which will help elucidate the changes in muscle-tendon interaction during spaceflight.

他们在不同负荷条件下的跑步和抗阻训练中，收集了足底压、运动学和肌肉参数的数据，并结合轨道驻留时间的影响，这将有助于阐明太空飞行期间肌肉-肌腱相互作用的变化。

" In older people, an exercise program appears important for brain maintenance, " says Daniel M. Landers, professor of exercise science at Arizona State University, who recently published an article reviewing the scientific literature on activity's effect on the brain.

亚利桑那州立大学的运动学教授丹尼尔? M. 兰德斯最近发表了一篇文章，对有运动对大脑影响的科学文献进行了综述。他说：“对老年人来说，锻炼划对维持大脑功能显得非常重要。”
