কক্ষীয় বেগ

কোনো এটা বস্তু, যেনে উপগ্ৰহ, যি বেগত থাকিলে কক্ষ পথত থাকিব পাৰে৷

Orbital velocity, velocity sufficient to cause a natural or artificial satellite to remain in orbit. Inertia of the moving body tends to make it move on in a straight line, while gravitational force tends to pull it down. The orbital path, elliptical or circular, thus represents a balance between gravity and inertia.
