Learn how to calculate the orbital velocity of a satellite around the Earth using the concepts of gravitational force and centripetal force. See the formula, steps and examples with diagrams and FAQs.
- Orbital velocity is defined as the minimum velocity a body must maintain to stay in orbit.
- Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to...
- Gravity is everywhere. It gives shape to the orbits of the planets, the solar system, and even galaxies. Gravity from the Sun reaches throughout th...
- If the object moves only under the influence of gravity it is called free fall.
- The acceleration due to gravity is independent of the mass of the body.
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most ...
Orbital Velocity is the velocity at which a body revolves around another body. It is an important concept in the field of astronomy and physics. It is used extensively to launch satellites into orbits and to make sure that they stay in their orbits.
Oct 19, 2023 · Orbital velocity is the velocity at which a body must travel to remain in orbit. “Does the moon also fall? If it does, then why hasn’t it crashed into Earth just like the apple?”

Orbital velocity is the velocity of a satellite that keeps it in orbit around a planet or other body. Learn how orbital velocity depends on the mass, distance, and shape of the orbit, and see examples of orbital velocities in different situations.

Sep 12, 2022 · Determining the orbital speed and orbital period of a satellite is much easier for circular orbits, so we make that assumption in the derivation that follows. As we described in the previous section, an object with negative total energy is gravitationally bound and therefore is in orbit.
Learn about the three laws of planetary motion that describe the orbits of planets and other celestial bodies. The third law relates the orbital period and the square of the semi-major axis of an orbit.
