Final answer:Mechanical energy,which is the energy associated with the motion and position of an object, is the sum of kinetic and potential energy.Kinetic energyis related to motion, whereas potential energy is related to the position or state of the object, such as its height above ground.Explanation:The energy associated with the motion and position of an object is calledMechanical Energy, which is a combination of kinetic energy and potential energy.Kinetic Energyis the energy associated with the motion of a particle, single body, or a system of objects moving together. An example of kinetic energy would be a thrown ball travelling through the air.Potential Energyis sometimes known as stored energy and comes in several forms, one of which isGravitational Potential Energy. This type of energy is dependent on the object's position above Earth's surface or another object in space. A classic example is a roller coaster car at the top of a hill - it has plenty of gravitational potential energy that will be converted into kinetic energy as it descends.The sum of an object's kinetic and potential energy is referred to as its mechanical energy, which can be transferred into or out of a system when an external force is applied. An essential principle in physics is that the total mechanical energy in a system is always conserved.Learn more about Mechanical Energy here:brainly.com/question/34112071#SPJ11...
