SUMMARY
The kinetic energy of a particle is directly related to the square of its velocity, as defined by the equation KE = 0.5 * m * v², where KE is kinetic energy, m is mass, and v is velocity. If the velocity of the particle is decreased by a specific factor, the kinetic energy will decrease by the square of that factor. For example, if the velocity is halved, the kinetic energy will be reduced to one-fourth of its original value. This relationship is fundamental in classical mechanics and applies universally to all particles.
