what is energy? Energy is the ability to do work
what are the two states of energy? Potential and kinetic energy
what does the law of conservation of energy state? The law of conservation of energy states that energy can neither be created or destroyed
How is speed related to energy? The faster the speed the more energy is used up
How is energy acquired? Energy is acquired by the work that is done on an object
Energy is needed to do ____ work
what is potential energy? Potential energy is stored energy as a result of an object's position
what are the two types of potential energy? Gravitational potential energy and Elastic potential energy
what is Gravitational potential energy? Gravitational potential energy is the stored energy in an object due to its height or distance above the ground
what does gravitational potential energy depend on? It depends on the mass of an object and the height of an object
what is Elastic potential energy? Elastic potential energy is the energy stored in an object due to a change in its usual position
what does Elastic potential energy depend on? Elastic potential energy depends on how much an object is changed from its regular position
what is kinetic energy? kinetic energy is the energy of an object in motion
what does kinetic energy depend on? Kinetic energy depends on the speed of an object and the mass of an object
Can potential energy be translated into kinetic energy? YES. Potential energy can be translated into kinetic energy
Kinetic energy increases with _________ and ______ speed and mass
what is the relationship between temperature and kinetic energy? temperature is the direct measure of kinetic energy
what is mechanical energy? Mechanical energy is the sum of the kinetic and potential energies in an object
what are the two forms of mechanical energy? kinetic and potential
What will an object gain if it loses mechanical energy? the object will gain heat or an increase in temperature
what is chemical energy? Chemical energy is the energy stored in the bonds of chemical compounds
How is chemical energy released? Chemical energy is released through chemical reactions
what is nuclear energy? The energy that comes from the nucleus of an atom
what is electrical energy? Electrical energy is energy carried by moving electrons in an electric conductor
