What correctly describes the difference in kinetic energy between the two cars?

The car converts chemical energy to mechanical energy in the engine, by combining carbon in the fuel with oxygen from the air to create carbon dioxide that goes out of the exhaust (hydrogen in the fuel is also combined with oxygen to create water vapour).
The heat generated by these chemical processes drives the piston, the crankshaft and the car.
The mechanical energy is transferred into kinetic energy as the car moves forward, and into potential energy if the car climbs a hill.
When the time comes to stop, the kinetic energy of the car is converted into heat by friction in the brakes.

What is difference between end point and kinetic assay in biochemistry?
No one knows
What is the difference between potential and kinetic energy in a ven diagram?
Potential energy is energy a body has due to its position. Kinetic energy is energy a body has due to its motion.
Difference between potential and kenetic energy?
Potential energy is when the particles are at rest and kinetic energy is when the particles are in motion.
Compare potential and kinetic energy?
The difference between potential and kinetic energy all comes down to a very simple property of the object. If an object is moving, then it has kinetic energy, or kinetic energy is the energy of movement. Potential energy is energy that is stored in an object and can be released under the right conditions.
What is the difference between piezoelectricity and pyroelectricity?
consider a triangle where each corner represents kinetic, electrical n thermal. the side bw thermal and electrical rep the pyroelectricity and it produces no kinetic The side bw thermal and kinetic rep the piezoelectricity and it produces no heat

What is the difference between thermodynamic and kinetic stability?
Kinetic - how quickly something reacts.Thermodynamic - the energies required.
What term describes the of energy between objects that have different average thermal kinetic energies?
heat
What term describes the transfer of energy between objects that have different average thermal kinetic energies?
heat
What terms describes the transfer of energies between objects that have different average thermal kinetic energies?
heat
Mechanical energy is the difference between the kinetic and potential energies of an object?
true

What is the difference between kinetic and potential enrgy?
Kinetic energy is the motion of an object (real). Potential energy is a measure of the kinetic energy an object WOULD have if it were to be released and allowed to fall.
What is the same and the difference between potential and kinetic energy?
Potential is stored energy and Kinetic is just simple movement like windmills are powerd with Kinetic energy. They are both energy.
What is the difference between solids liquids and gases in terms of kinetic energy?
Solids have the lowers and gases the highest kinetic energy. Liquids are in the middle.
What is the difference between static and kinetic?
Kinetic means 'caused by some form of motion'. Static means 'built up by lack of motion'.
