Kinetic and Potential Energy
... Energy is defined as the ability to do work or cause change. Energy can be the ability to do work (potential energy) or the energy it has due to its motion (kinetic energy). Kinetic Energy (KE) or the energy of motion (kine = motion in Greek) is determined by the mass of the object and its velocity ...

Quest:
... The amount of energy an object has because of its location is dependent on the mass of the object, times the acceleration due to gravity at that point (for us, almost always -9.8 m/s2), times the height from which it can fall from. The object is said to have Potential Energy, or PE, because it could ...

Work Energy KE PPT from class
... The Work Energy Theorem And so what we really have is called the WORK-ENERGY THEOREM. It basically means that if we impart work to an object it will undergo a CHANGE in speed and thus a change in KINETIC ENERGY. Since both WORK and KINETIC ENERGY are expressed in JOULES, they are EQUIVALENT TERMS! ...
