What is meant by orbital velocity?
Orbital velocity is the speed required to achieve orbit around a celestial body, such as a planet or a star.
What is the best definition of orbital velocity?
Orbital-velocity meaning The minimum velocity required to place or maintain a satellite in a given orbit. noun. 2. 4. The velocity at which a body revolves about another body.
What is the velocity of orbital velocity?
Near the surface of the Earth, if air resistance could be disregarded, orbital velocity would be about eight kilometres (five miles) per second. The farther from the centre of attraction a satellite is, the weaker the gravitational force and the less velocity it needs to remain in orbit.
What is orbital velocity and its derivation?
The equation of the orbital velocity is given by: Vorbit=√GMR. In the above equation, G stands for Gravitational Constant, M stands for the mass of the body at the center and R is the radius of the orbit. The Orbital Velocity Equation is used to find the orbital velocity of a planet if its mass M and radius R are known …
What is orbital velocity class 11th?
Orbital velocity is defined as the minimum velocity a body must maintain to stay in orbit. Due to the inertia of the moving body, the body has a tendency to move on in a straight line.
What is orbital velocity for Class 11th?
Orbital velocity is defined as the minimum velocity a body must maintain to stay in orbit. Due to the inertia of the moving body, the body has a tendency to move on in a straight line. But, the gravitational force tends to pull it down.
What is the planet with the greatest orbital velocity?
Mercury is the fastest planet, which speeds around the sun at 47.87 km/s. In miles per hour this equates to a whopping 107,082 miles per hour. 2. Venus is the second fastest planet with an orbital speed of 35.02 km/s, or 78,337 miles per hour.
What is the equation for orbital speed?
Orbital speed equation is given by, vorbit = √GM / R. vorbit = √6.673×10−11 ×8.35×1022 / 2.7×106. = 20.636 x 106 m/s. Example 2. The mass of the Jupiter is given by 2.89×1027 Kg and the radius is given as 71400 km, determine the orbital speed.
What do you mean by orbital velocity/?
Orbital-velocity definitions The velocity at which a body revolves about another body.
What do planets orbital velocity mean?
Orbital velocity is the speed required to achieve orbit around a celestial body, such as a planet or a star. This requires traveling at a sustained speed that: Is fast enough to counteract the force of gravity pulling the orbiting object toward the body’s surface
