In classical mechanics, the kinetic energy is denoted T. Why not K? In QM the kinetic energy operator is sometimes denoted by T as well although I have seen it denoted as K.
Kinetic energy is the energy that an object possesses due to its motion. It is a scalar quantity and is dependent on an object's mass and velocity.
The formula for calculating kinetic energy is KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity.
Translational kinetic energy is the energy an object possesses due to its linear motion, while rotational kinetic energy is the energy an object possesses due to its rotational motion.
Yes, kinetic energy can be converted into other forms of energy, such as potential energy, thermal energy, or sound energy, depending on the situation.
In quantum mechanics, kinetic energy is represented by the operator T and is used to describe the energy of a particle in motion. This is different from classical mechanics, where kinetic energy is a measurable quantity.
