Definition
This equation represents the kinetic energy (KE) of an object in motion, where m is the mass and v is the velocity. It quantifies how much energy an object possesses due to its motion.
Conservation of energy states that in a closed system, total energy remains constant over time. In other words, energy cannot be created or destroyed but can only change forms.
Work-Energy Theorem: The work-energy theorem states that the work done on an object is equal to its change in kinetic energy. It relates force, displacement, and changes in kinetic energy.
