mechanical energy
No, the energy of a moving car is proportional to the square of its speed. So, a car traveling at 60 mph carries four times the energy as the same car traveling at 30 mph.
A car traveling at 45 mph has kinetic energy, which is the energy of motion. As the car moves, its speed and mass contribute to its kinetic energy. This energy is what enables the car to perform work and overcome resistance while in motion.
A car traveling at a higher speed will have more kinetic energy than a car moving at a slower speed. So, the car with the most kinetic energy would be the one traveling at the highest speed.

The energy related to movement is called kinetic energy.
The main type of energy associated with a race car traveling at its maximum speed is kinetic energy, which is the energy of motion. At its top speed, the car has converted potential energy stored in its fuel and other systems into kinetic energy as it moves.
60. K= 1/2mv^2 therefore when v is larger, there is more kinetic energy
Kinetic Energy is defined as the energy associated with motion. This is in contrast to potential energy which is associated with an entity's energy at rest, and it's potential for motion. Kinetic Energy can be calculated using this formula: KE = 0.5*Mass*Velocity^2, where KE = Kinetic Energy It is apparent by the formula that the same car traveling at a higher speed will have a greater kinetic energy than it does when traveling at a lower speed. Therefore, when the car travels at 50 mi/hr it has a higher kinetic energy than when it travels at 35 mi/hr. Let me just note that if we were talking about two different cars then we'd have to consider the weights of the cars.
4 times (from v squared)
The engine doesn't have to use as much fuel when the car is traveling downhill.
A car is not energy; it may have energy. The energy related to movement is called kinetic energy.
The formula for kinetic energy is KE = 0.5 * mass * velocity^2. Plugging in the given values, the kinetic energy of the 1600 kg car traveling at 12.5 m/s would be: KE = 0.5 * 1600 kg * (12.5 m/s)^2 = 125,000 Joules.
