What is kinetic energy, and how is it defined?

  • 0

Kinetic energy is the energy possessed by an object due to its motion. It is defined as the work done on the object to make it acquire a certain velocity.

  1. Kinetic energy is the energy possessed by an object due to its motion. It is defined by the equation KE = 0.5 × mass × velocity². In this formula, KE represents kinetic energy, mass is the object’s mass, and velocity is its speed. The concept highlights that the energy of a moving object depends on both its mass and the square of its velocity. The greater the mass or velocity, the higher the kinetic energy. This fundamental principle underlies the understanding of how motion translates into energy, applicable across various scales from macroscopic objects to microscopic particles.
