Abstract:
The orientation of organisms in space and their morphogenesis in relation to the gravitational field of the Earth are the main topics of research in the field of gravitational biology. For more than 100 years clinostats provided the only possibility to simulate physiological weightlessness. In contrast to animals, plants are characterized by intracellular gravireceptors. Nevertheless, there are some indications, e.g., the minimal energy of approx. 10(-18) J triggering a gravity-dependent response, for similar mechanisms of gravity perception. Stretch-activated ion channels might be the common structural basis.

Acceleration due to Gravity on Other Planets
Astronomical observations are thus used to measure the acceleration due to gravity on other planets. This can be determined by observing the effect of a planet's gravity on objects close to it. The crucial factor that helps in this...

Measuring Acceleration Due to Gravity
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...

Work Done by Gravity
Like other forces, gravity does work on an object if it displaces it toward the Earth's center. In this case, the work done by gravity is said to be positive. If an external force acts on the object against the pull of gravity and manages to lift it away from the Earth's center, work is done against gravity. In this case, the net work done is said to be negative.
