How can total energy be conserved while energy of motion is not?
If you think of a car, fuel is burnt to make the car move. Chemical energy into kinetic energy. The reason the car stops when the fuel runs out is because the car is having to work against forces acting against it like friction with the road, air resistance and gravity acting on it's own mass.The cars motion or kinetic energy is converted into kinetic energy in the particles in the air and heat due to friction.
Is the total angular momentum conserved when there is a two car collision?
In a two-car collision, the total angular momentum is conserved only if no external torque is acting on the system. If there is no net external torque exerted on the cars during the collision, the total angular momentum before the collision will be equal to the total angular momentum after the collision.
Why in a collision momentum is not always conserved?
In principle momentum is always conserved. However what sometimes happens in a collision is that energy is released that is then no longer considered part of the system. For example if two cars collide energy could be dissipated via the air and ground (e.g. heat) and this can also carry away momentum. Often, these effects are not taken into account and in that way momentum conservation appears to be violated; but if one takes care and takes into account all collision products the total momentum after is equal to the total momentum prior. So in short, any violation can be traced back to a redefinition of the system.
How was energy conserved during mouse trap car races?
the elastic potential energy of the spring on the mouse trap is changed to kinetic energy, causing the car to move. The kinetic energy in turn changes to thermal energy as friction causes the car to come to a halt
How is the energy of the universe conserved during the combustion of gasoline in a car engine?
During the combustion of gasoline in a car engine, the chemical energy stored in gasoline is converted into thermal energy through combustion. This thermal energy is then used to power the engine and drive the vehicle. While there may be some energy lost as heat or sound during combustion, the total energy of the system (including the car, gasoline, and surroundings) remains constant, thus conserving the energy of the universe.
How is energy conserved when a car runs out of gas and stops?
When the car has no gas, no energy is used and no energy is produced.

A quantity which is conserved in the collision of a car and a truck is?
Total momentum
How is energy conserved when a car hits another car during an accident?
Most of the mechanical (or kinetic) energy is converted to heat.
How was energy conserved during mouse trap car races?
the elastic potential energy of the spring on the mouse trap is changed to kinetic energy, causing the car to move. The kinetic energy in turn changes to thermal energy as friction causes the car to come to a halt
How is energy conserved when a car is going down a hill with no brakes?
The engine doesn't have to use as much fuel when the car is traveling downhill.
Is the total mechanical energy of bumper cars conserved?
If you keep your foot on the floor you are adding energy all the time, but if two cars meet without drive engaged, the total energy before and after must balance. Of course kinetic energy can be absorbed by the car's bodywork so the resultant kinetic energy will be altered by collisions. Some energy will also be absorbed by the floor and appear as heat due to friction.

This thermal energy is then used to power the engine and drive the vehicle. While there may be some energy lost as heat or sound during combustion, the total energy of the system (including the car, gasoline, and surroundings) remains constant, thus conserving the energy of the universe.
Explain how momentum is conserved when a car hits a bicycle?
When a car hits a bicycle, momentum is conserved because the total momentum of the system (car + bicycle) before the collision is equal to the total momentum after the collision. This means that the combined momentum of the car and bicycle remains constant despite the collision, with some of the momentum transferring between the two objects during the impact.
How is energy conserved when a car slows down?
When a car slows down, its kinetic energy decreases as it loses speed. This kinetic energy is converted into other forms of energy, such as heat generated by the brakes and friction between the tires and the road. Thus, energy is conserved through this conversion process.
