Weightlessness01:01

Weightlessness

5.4K
When an object is dropped, it accelerates toward the center of the Earth. If the net external force on the object is its weight, it is said to be in free fall; that is, the only force acting on the object is gravity. Galileo was instrumental in showing that, in the absence of air resistance, all objects fall with the same acceleration g. However, when objects on the Earth fall downward, they are never truly in free fall, because there is always some upward resistance force from the air acting...

Measuring Acceleration Due to Gravity

1.4K
Consider a coffee mug hanging on a hook in a pantry. If the mug gets knocked, it oscillates back and forth like a pendulum until the oscillations die out.
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...

  • 评估AG静态耐受性数据在太空飞行模拟研究中有效使用的时间.

主要方法:

  • 在7个月间进行的两次AG静态耐受性测试的二次分析.
  • 涉及4名男性和3名女性,他们参加了两次测试.
  • 利用林的一致性相关系数 (LCCC) 来比较时间到临前和心率反应.

主要成果:

  • 在男性的两个测试日期 (LCCC = 0.98),但不是女性 (LCCC = -0.64).
  • 平均心率反应显示所有参与者 (不包括一个女性) 的测试之间存在强烈的线性相关性.
  • 在男性中,尽管心率基线不同,但高LCCC对于临近昏的时间是可以实现的.

结论:

  • 使用AG的正静性耐受性测试可能在男性中有效期长达7个月.
  • 建议对更大的男性和女性队伍进行进一步的调查,以证实这些发现.
