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, PhysicsEnergy is the ability to perform the necessary task. Plants and living organisms require energy for their reproduction and survival. The sun is the most crucial energy source, but all living beings cannot utilise solar energy directly. The conversion of energy is significant for proper utilisation to support life’s activities. Plants use the process of

Class 11, Conservation of energy, IIT JEE, Physics, Work, Energy, and PowerA solar cooker is a device that cooks food by employing the energy generated by the Sun, i.e. solar radiation. Cooking vegetables, meat, and rice on stoves and ovens is common. We can prepare the same meal with a solar cooker, except using gas or electricity, we may use a naturally available resource: sunlight. It
Whenever we compress or lengthen a stretched spring, we experience a force equivalent to the force we apply in the opposite direction. However, as soon as the stress is relieved, the spring returns to its original shape. The spring potential energy is what it’s called. Potential Energy of a Spring A spring can be found

Class 11, Conservation of energy, IIT JEE, Physics, Work, Energy, and PowerIf the core of a substantial particle, uranium, retains a neutron, the core can become unsound and parted. This is called Nuclear Fission. Splitting delivers energy as hotness. Even though splitting can usually happen, parting as experienced in the advanced world is typically a purposeful manufactured atomic response. Normal parting occasions discharge around 200,000,000 eV

Class 11, Conservation of energy, IIT JEE, Physics, Work, Energy, and PowerMechanical energy Introduction The phrase “energy” refers to a person’s capacity to function. Mechanical energy, potential energy, chemical energy, kinetic energy, thermal energy, solar energy, and other energy types. Let us take a closer look at the conservation of mechanical energy under this post. Definition of mechanical energy The total possible energy and dynamic energy
Before special relativity, mass and energy were considered separate things in theoretical approaches. The mass-energy relation, E = mc2, is an equation in Albert Einstein’s special relativity theory that states that mass and energy are the same physical objects that may be converted into one another. The energy (E) of a body is equal to

Class 11, Conservation of energy, IIT JEE, Physics, Work, Energy, and PowerBefore special relativity, mass and energy were considered separate things in theoretical approaches. The mass-energy relation, E = mc2, is an equation in Albert Einstein’s particular relativity theory that states that mass and energy are the same and that they may be converted into one another. The kinetic energy (E) of a body is equal
