The energy of an object, owing to its movement, is called kinetic energy. A ball rolling on the floor is said to have kinetic energy. A stationary roller coaster has potential energy. When it starts to roll, potential energy changes to kinetic energy. When the roller coaster comes to a h...
In science, the kinetic energy (KE) of an object is the energy that it has because of its movement. It is the work that is expected to quicken a body of a givenmassfrom rest to its expressed speed. While picking up the energy during its quickening process. The body keeps up this kin...
In the context of astronomy, aphelion refers to the furthest distance between the center of an object and the center of another object that orbits the first object. In the case of Earth, the first object is the sun.Answer and Explanation: ...
Planck's constant has the same units as angular momentum, or the momentum of an object moving in a circle. So Bohr imported this idea to electrons orbiting a nucleus, saying that the smallest possible orbit of an electron would equal the angular momentum of exactly one Planck constant. Higher...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
The discovery of two more planetary systems in the universe was announced by astronomers in early 2001. Each is different from the other and from our solar system. In one, a star like our Sun is orbited by a massive planet and an even larger object seventeen times the size of Jupiter. ...
Gravitational Potential Energy:Gravitational Potential Energy is the stored energy an object has due to its location within the gravitational field of another object. For example, a satellite orbiting the Earth. An object is defined to have zero gravitational potential...
Energy as a concept emerged out of the idea of living force, which was defined as the product if the mass of an object and its velocity squared. It is believed that the living force is conserved. The law of conservation of energy was first postulated in the 19th century. It was applied...
Rotational energy of an object. Homework Statement An object, consisting of two point masses with mass m are connected by a rigid shaft with negligible mass. They are lying horizontally at rest. One of the point masses is instantly given a speed of v. Calculate the total energy of the syst...
An object that is not moving has the least kinetic energy because kinetic energy is the energy possessed by an object due to its motion. Since the object is not moving, it does not possess any kinetic energy. In contrast, a satellite that is orbiting in space and a car that is running...
