Key Terminology & Definitions
Kinetic Energy (KE = ½mv²)
The energy an object possesses due to its motion, defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Joule (J)
The SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of the force.
