Not sure of your exact reference, but car possesses potential energy as it sits. Gas or battery (chemical or electrical energy) transform to kinetic energy as it goes. Since energy is neither created nor destroyed, various things are at work like heat energy that dissipate the energy of motion.
What else can I help you with?
How is energy lost in a toy car?
Friction and wind resistance.
What type of energy is lost as a car goes up a hill?
As a car goes up a hill, kinetic energy is converted into gravitational potential energy, resulting in a loss of kinetic energy. Additionally, some energy is lost as thermal energy due to friction in the engine and between the tires and the road. This energy loss manifests as heat, reducing the car's overall efficiency as it climbs the incline.
A car has 40000000J of energy available in its tank and assuming a constant force of 1000N is available to move the car and neglecting the energy lost as heat. How far the car will travel?
40KM.
How does a hybrid conserve energy?
In a hyrid car, when you brake the energy that is used is transferred back into electricity instead of totally lost as heat energy.
Is the total energy of the car always conserved?
Basically, in physics, total energy is always conserved. Of course, it is possible for some of the energy from a car to go somewhere else.
How much energy did Car 1 lose from the top to the bottom of the hill?
The energy lost by Car 1 is equal to its initial potential energy at the top of the hill minus its final potential energy at the bottom. This can be calculated using the formula: Energy lost = mgh_top - mgh_bottom, where m is the mass of the car, g is the acceleration due to gravity, and h_top and h_bottom are the heights of the top and bottom of the hill, respectively.
Why is a typical car engine only 30 percent efficient?
Most of the energy is lost as heat.
What percentage of the energy from gasoline in a car is transformed into motion?
Roughly 15-30% of the energy from gasoline in a car is transformed into motion. The rest is lost as heat through the engine and exhaust system.
Is all the energy in gasoline used to run the car?
No, not all the energy in gasoline is used to run the car. Most of the energy is lost as heat in the engine and exhaust system, with only about 20-30% being converted into mechanical energy to move the vehicle.
How does a car engine convert petrol to power?
The petrol is burned in the engine where part of the energy released (roughly one-fourth) is used in moving the car, while the rest is lost as heat and sound energy.
A car's motor does 2500 kJ of work in moving the car however the car only has 18 kJ of kinetic energy. Explain how this can happen?
The car's motor does work to transfer energy, a portion of which is used for purposes other than kinetic energy, such as overcoming friction, air resistance, or internal mechanical losses. Therefore, not all the energy output by the motor contributes to the car's kinetic energy, resulting in a discrepancy between the work done by the motor and the car's kinetic energy.
Is energy lost when energy changes?
Energy is never lost or destroyed.
