قوة الجاذبية
نوع: محتوى تعليمي
لعظم حجم الأرض وكثافتها فهي شديدة الجذب للأشياء التي فوق سطحها أو بالقرب منها، ويسمى هذا قوة الجاذبية، التي تمسك الغلاف الجوي والغلاف المائي على سطح الأرض، وتحدد وزن الأشياء جميعًا. وقوة الجاذبية في واقع الأمر تمسك الأرض من التفكك وتجذب جميع الأشياء التي فوقها، وهي من المسلمات لدى أي إنسان، وكل ذلك بأمر الله ومشيئته.

A comparative diagram illustrating the relative sizes of several celestial bodies. From largest to smallest, the labeled bodies are: المشتري (Jupiter), زحل (Saturn), أورانوس (Uranus), نبتون (Neptune), الأرض (Earth), الزهرة (Venus), المريخ (Mars), عطارد (Mercury), and بلوتو (Pluto). Jupiter and Saturn are significantly larger than the ice giants Uranus and Neptune, which are in turn larger than the terrestrial planets Earth, Venus, Mars, and Mercury. Pluto is shown as the smallest, a dwarf planet.
A comparative diagram showcasing the immense size of the Sun relative to several planets. The Sun (الشمس) is depicted as a massive yellow sphere on the left. To its right, Jupiter (المشتري) is shown as a large, striped planet, significantly smaller than the Sun but much larger than Earth (الأرض), which appears as a small blue sphere next to Jupiter. Other smaller, unlabeled planets are visible as tiny dots near Earth, further emphasizing the scale.
الجاذبية في الفضاء
A photograph of an astronaut in a full white spacesuit, floating in the darkness of space. The astronaut's visor reflects the Earth, which is visible in the background, illuminated by city lights on its night side. The Earth's blue and white cloud patterns are also discernible. The astronaut appears to be in a state of weightlessness.

**DIAGRAM**: Untitled
Description: A comparative diagram illustrating the relative sizes of several celestial bodies. From largest to smallest, the labeled bodies are: المشتري (Jupiter), زحل (Saturn), أورانوس (Uranus), نبتون (Neptune), الأرض (Earth), الزهرة (Venus), المريخ (Mars), عطارد (Mercury), and بلوتو (Pluto). Jupiter and Saturn are significantly larger than the ice giants Uranus and Neptune, which are in turn larger than the terrestrial planets Earth, Venus, Mars, and Mercury. Pluto is shown as the smallest, a dwarf planet.
Context: This diagram visually represents the vast differences in physical size among planets and dwarf planets within our solar system, providing a scale for understanding their relative dimensions.

Other smaller, unlabeled planets are visible as tiny dots near Earth, further emphasizing the scale.
Context: This diagram highlights the dominant size of the Sun in our solar system, illustrating how even the largest planet, Jupiter, and Earth, are dwarfed by the star's magnitude.
