Energy is the indirectly observed quantity that has power to cause a change in a system. We do not observe energy directly - we only observe the effects that it has on systems as they change.
According to the first law of thermodynamics, the energy of an isolated system (one where no mass or energy are entering or leaving) must remain constant.
Energy never disappears it just forms into another type of energy

What best describes mechanical energy?
combined potential and kinetic energy (:mass and velocity
Which describes the energy conversions used to make a car down the street?
Assuming it just rolls down a slope, without the engines working: gravitational potential energy will be converted to kinetic energy. The kinetic energy will eventually be converted to heat energy.
Kinetic energy is the energy of?
Motion.
Energy in the form of motion?
The energy of motion is called kinetic energy.
What are the two main forms of energy?
The two main forms of energy are Kinetic energy and Potential Energy. Kinetic energy is motion energy. Potential energy is energy stored in matter.
What best describes temperature of substance?
average kinetic energy
Which best describes the energy conversion that happens when hydroelectric power plants are used to make electricity?
Kinetic energy to electrical energy
Which best describes the energy conversation that happens when windmills are used to make electricity?
Kinetic energy to electrical energy
What best describes the motion on iron atoms in solid iron?
Kinetic energy best describes the motion of the particles in a piece of steel.
What best describes mechanical energy?
combined potential and kinetic energy (:mass and velocity
What best describes the process of water vapor cooling down as it rises and forming clouds?
changing heat energy into kinetic energy
What is the best summary of kinetic energy?
The best summary of kinetic energy is energy of motion. Kinetic energy is only present where there is motion in an object. Friction generates more kinetic energy.
What describes this energy transformation from the turning turbine to electricity?
kinetic energy into electric energy
Mechanical energy describes what energy?
combined potential and kinetic energy (:mass and velocity
The energy of matter in motion is called?
kinetic energykinetic energy is best to be proven as george cliffton sizemore
What KE describes the way energy is stored in a moving cricket bat?
KE means "kinetic energy" in this case. Kinetic energy refers to the energy of moving objects.
What best describes the motion of molecules?
um .... its the kinetic energy which helps to move the molecules when the thing is hot then the kinetic energy helps the molecules move faster and when things are some what cold then the kinetic energy moves slower . the thing may be food or etc ...... .
