When calculating the orbit of a satellite around a planet in space exploration, we need to use a lot of mathematical formulas. One of the important concepts is "elliptical orbit". The word "elliptical" is related to the shape which is like ___. A....
Is ___48 hours___ the man- made satellite ___ is made in our country to orbit the planet around? A.it; that; where B.it; when; what C.it for; that it takes; that D.it; that it takes; whic
Why doesn't the force of gravity change the speed of a satellite in circular orbit? A student makes a hypothesis that the period of a pendulum depends upon the hanging weight. The student is provided with string attached to the ceiling, several masses, a ruler, and ...

Why doesn't the force of gravity change the speed of a satellite in circular orbit? Why is the coefficient of kinetic friction less than static friction? What is the net force that acts on a 10N freely falling object? Why does tilting an object that is stable r...
The term "perihelion" refers to the point in the orbit of a planet or other astronomical body, at which it is closest to the sun. The word comes from Greek and literally means around (peri) the sun (helios). Aphelion is the point at which an orbiting body is furthest from the sun...

Artist's conception of the Epsilon Indi system. The two brown dwarfs orbit their common center of mass, which in turn orbits the much more distant primary component, a Sun-like star. By mapping the orbital motion of the brown dwarfs, the team was able to determine their masses. Much like...
