Average Acceleration01:30

Average Acceleration

The importance of understanding acceleration spans our day-to-day experiences, as well as the vast reaches of outer space and the tiny world of subatomic physics. In everyday conversation, to accelerate means to speed up. For instance, we are familiar with the acceleration of our car; the harder we apply our foot to the gas pedal, the faster we accelerate. The greater the acceleration, the greater the change in velocity over a given time. Acceleration is widely seen in experimental physics. In...
Gyroscope01:02

Gyroscope

A gyroscope is defined as a spinning disk in which the axis of rotation is free to assume any orientation. When spinning, the orientation of the spin axis is unaffected by the orientation of the body that encloses it. The body or vehicle enclosing the gyroscope can be moved from place to place, while the orientation of the spin axis remains the same. This makes gyroscopes very useful in navigation, especially where magnetic compasses cannot be used, such as in crewed and crewless spacecraft,...
Gyroscope: Precession01:24

Gyroscope: Precession

Precession can be demonstrated effectively through a spinning top. If a spinning top is placed on a flat surface near the surface of the Earth at a vertical angle and is not spinning, it will fall over due to the force of gravity producing a torque acting on its center of mass. However, if the top is spinning on its axis, it precesses about the vertical direction, rather than topple over due to this torque. Precessional motion is a combination of a steady circular motion of the axis and the...
Measuring Acceleration Due to Gravity01:12

Measuring Acceleration Due to Gravity

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...
Relative Motion Analysis - Acceleration01:10

Relative Motion Analysis - Acceleration

A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...
Relative Motion Analysis using Rotating Axes - Acceleration01:22

Relative Motion Analysis using Rotating Axes - Acceleration

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame. The absolute velocity of point B is determined by adding the absolute velocity of point A, the relative velocity of point B in the rotating frame, and the effects caused by the angular velocity within the rotating frame.
Time differentiation is...

Area of Science:

  • Space physics
  • Fluid dynamics
  • Materials science

Background:

  • The TRAMP experiment on Foton 12 aimed to measure Thermal Radiation Forces (TRF).
  • Spacecraft rotation induced convective motions, and corrosion led to gas bubbles, compromising the primary objective.
  • These issues prevented the direct measurement of TRF.

Purpose of the Study:

  • To reveal and measure Thermal Radiation Forces (TRF).
  • To assess the impact of convective motions and gas bubbles on microgravity experiments.
  • To evaluate the TRAMP experiment's potential as a sensitive accelerometer.

Main Methods:

  • Utilized the TRAMP space experiment aboard the Foton 12 mission.
  • Observed and analyzed particle migration and fluid behavior under microgravity conditions.
  • Compared acceleration data derived from velocity measurements with data from the Quasi-Steady Acceleration Measurement (QSAM) system.

Main Results:

  • The experiment failed to measure Thermal Radiation Forces (TRF) due to experimental disturbances.
  • Undesired convective motions and gas bubbles significantly compromised the results.
  • Acceleration data deduced from velocity measurements strongly correlated with QSAM system data.

Conclusions:

  • The TRAMP experiment, despite failing its primary objective, demonstrated high sensitivity as an accelerometer.
  • Microgravity experiments require careful consideration of factors like spacecraft rotation and material stability.
  • The findings highlight the potential for repurposing experimental apparatus for unexpected scientific insights.
