Launching Objects Into Space
Description
Space travel is based on understanding the force of gravity and the ability to accelerate objects to speeds that allow them to break free from it or enter orbit around the Earth. The video demonstrates the physical principles behind the launch of satellites and spacecraft, ranging from escape velocity to orbital motion.

שיגור עצמים לחלל
המסע לחלל מבוסס על הבנת כוח הכבידה והיכולת להאיץ עצמים למהירות שתאפשר להם להשתחרר ממנו או להיכנס למסלול סביב כדור הארץ. הסרטון מדגים את העקרונות הפיזיקליים העומדים מאחורי שיגור לוויינים וחלליות, החל ממהירות המילוט ועד לתנועה במסלול הקפי.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
