What is an ellipse? The ellipse is one of the four traditional conic sections and is made by the slicing of a cone with a plane. The parabola, circle, and hyperbola are the other conic sections. The conic sections that planets and other celestial objects in the solar system trace out are also called ellipses, […]
In astronomy, an eclipse occurs when an astronomical object is temporarily covered by another body, either by passing into the shadow of another body or by having another body pass between the astronomical object and the observer. A syzygy is a celestial alignment in which three celestial objects are in perfect alignment with one another.
Dwarf planets are celestial bodies which orbit the Sun in a straight orbit. Unlike other planets, it is large enough to be drawn into a nearly spherical form by gravity and has not pushed other smaller celestial objects out of its orbital path. Astronomers estimate that the solar system and Kuiper Belt include up to 200
Which stream to choose after 10th? Newton’s law of gravitation proposed by Sir Issac Newton in 1687 stated that the force of attraction between two objects is directly proportional to the product of masses of the two objects and is inversely proportional to the square of the distance between the two. Newton’s law of gravitation

Class 11, Gravitation, IIT JEE, Kepler’s laws of planetary motion, PhysicsAround the equator is the best place to build an efficient space transportation system. Rockets can’t be launched when they’re far away from the equator. This means that the satellite weight has to be cut down. Currently, India has a rocket launch site in Sriharikota, called the Satish Dhawan Space Centre, Sriharikota. There are already

Class 11, Gravitation, IIT JEE, Orbital velocity and escape velocity, PhysicsTerminal velocity refers to the speed achieved by a freely falling object cutting through the fluids like water and air. It happens when the whole additional sum of the drag force (F d) and the buoyancy equals the falling force of gravity where the acceleration is zero and the net force acting on the object
The simplest way to understand the relationship between escape and orbital velocity is to learn how rockets take off. A push helps the rocket leave the Earth’s surface and enter the space circuit. The Earth’s gravitational field is powerful, and the objects need a hard ‘push’ to move against it and enter space. Escape velocity

Class 11, Gravitation, IIT JEE, Orbital velocity and escape velocity, PhysicsIn physics, escape velocity is the minimum speed required for a free, non-propelled object to escape the gravitational effects of a massive body. The minimum velocity required to escape the earth’s gravitational field or any planet is known as escape velocity. Escape velocity is only required to send a ballistic object on a trajectory that
