parabolic mirror in parallel paths‚ shown below. Headlights‚ spotlights‚ etc.‚ have the shape of a parabola to increase the intensity of the light and direct the light. The ellipse has similar reflective properties. Below you see three lines‚ blue‚ green and red. These lines start from either focus and ’bounce’ off the ellipse toward the other focus. As with the parabola‚ the angles between each signal and its tangent line segment (dark black) are equal. The parabola also amplifies any signal

Premium Planet Sun Mercury
Ganymede‚ a satellite revolving around Jupiter. One of the features of Mercury distinguishing it from other planets is that it has a different orbit loop. Whereas the orbit of most planets has the shape of a circle‚ the Mercury’s orbit has the shape of ellipse that looks like a stretched out circle. For that reason‚ the distance from Mercury to the sun varies from about 27 to 41 million miles. Mercury races around the sun faster than any other planet. A Mercurial year accounts only for 88 days‚ while our

Cartesian coordinates in three dimensions A three dimensional Cartesian coordinate system‚ with origin O and axis lines X‚ Y and Z‚ oriented as shown by the arrows. The tick marks on the axes are one length unit apart. The black dot shows the point with coordinatesX = 2‚ Y = 3‚ and Z = 4‚ or (2‚3‚4). Choosing a Cartesian coordinate system for a three-dimensional space means choosing an ordered triplet of lines (axes)‚ any two of them being perpendicular; a single unit of length for all three

his stand on these motions. The first law explains the shape of the orbit in which every planet moves around. It is shown by him that every planet follows an orbit that acts as an ellipse to the sun located at the center. This explains the movement of the planets around the sun day in and day out. Also known as the ellipse law‚ this law has helped engineers a great deal in monitoring the movement of the planets from one position to another. The focal point and the loci is always taken as the sun. The

Johannes Kepler‚ who was born December 27‚ 1571 and died on November 15‚ 1630. He created the three major laws of planetary motion. These three laws are called the Law of Ellipses‚ the Law of Equal Areas‚ and the Law of Harmonies. Kepler’s first law is called the Law of Ellispes or the Law of Orbits. This law states that planets move in elliptical orbits with the sun at one focus. Think of the elliptical shape as a part of a cone. This is the shape of the orbit that becomes an inverse square force
