What is the difference between a circle and an ellipse?
-- the eccentricity or -- the distance between the foci or -- the ratio of the major and minor axes
What is also known as the semimajor axis?
The major axis of an ellipse is its longest diameter, a line that runs through the center and both foci, its ends being at the widest points of the shape.The semi-major axis is one half of the major axis, and thus runs from the centre, through a focus, and to the edge of the ellipse. It represents a "long radius" of the ellipse, and is the "average" distance of an orbiting planet or moon from its parent body.
The eccentricity of the ellipse if minor axis is equal to the distance between the foci is Answer is 1 radical 2 how?
The standard equation for an ellipse centered at the origin is [x2/a2] + [y2/b2] = 1 We also have the relationship, b2 = a2 - c2 where c is the distance of the foci from the centre and a & b are the half lengths of the major and minor axes respectively. When the length of the minor axis equals the distance between the two foci then 2b = 2c : b = c. Thus, a2 =b2 + c2 = 2b2 One of the formulae for the eccentricity of an ellipse is, e = √[(a2 - b2)/a2] Thus, e = √[(2b2 - b2) / 2b2] = √½ = 1/√2.
How do you calculate the periapsis from an initial velocity and distance relative to a body?
To calculate the periapsis, you need to know the initial velocity and distance relative to a central body. The periapsis is the point of closest distance in an orbit. One way to calculate it is by using the specific orbital energy equation, which is the sum of the gravitational potential energy and the kinetic energy: ε = -(GM) / (2a), where ε is the specific orbital energy, G is the gravitational constant, M is the mass of the central body, and a is the semi-major axis of the orbit. The periapsis can then be determined by subtracting the distance relative to the central body from the semi-major axis.
Why is the distance formula important to geometry?
When we study the motion of body then its displacement is described on cartesian plane or in 3d geometry and not in real physical conditions,in this way to calculate the distance travelled by the body is a major aspect in calculating its speed and other things,and here distance formula help us to do so.There are many other importance of distance formula...
What is the formula for eccentricity?
eccentricity = distance between foci ________________ length of major axis
A planet's average distance from the sun is also what part of the orbital ellipse?
The semi-major axis.
A planet average distance from the sun is also What part of the orbital ellipse?
The semi-major axis.
How does the distance of planet affect its period of revolution?
The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.
What is the eccentricity of an ellipse in which the distance between the foci is 2 centimeters and the length of the major axis is 5 centimeters?
The eccentricity of that ellipse is 0.4 .
What are the angles of the planets eccentricities in relevance to the sun?
Kepler's Laws: The orbit of a planet is an ellipse with the Sun at one of the two foci. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.Eccentricity: the eccentricity of a planet's orbit is not an angle, it is a measure of how far each focus is from the centre of the ellipse. Most of the planets' orbits have low eccentricity so that the Sun's distance from the centre is the main effect of eccentricity.The Earth's orbit has an eccentricity of 1/60 so that the Sun is 149.6/60 million kilometres from the centre, approximately 2.5 million km. That means our distance from the Sun varies from 147.1 to 151.6 million km approximately.
Which planet moves the most slowly in its orbit?
Of the major planets, Neptune. The speed of planets in their orbits is directly related to their distance from the sun. The farther a planet is from the Sun, the slower its orbital speed.
What is the approximate eccentricity of it elliptical orbit?
The eccentricity measures how far off the centre each focus is, as a fraction of the distance from the centre to the extremity of the major axis.
What is the distance from one of the foci of the ellipse from its center?
The length of the semi-major axis multiplied by the eccentricity.
What is the eccentricity of an ellipse with a major axis of 54 cm and distance between the foci of 36.4 cm?
Dont know the eccentricity , but the minor axis = 39.888 cm (approx)
Which object comes after the sun in your solar system?
If you mean distance, the next major object it planet Mercury.If you mean distance, the next major object it planet Mercury.If you mean distance, the next major object it planet Mercury.If you mean distance, the next major object it planet Mercury.
