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.

In a closed system energy is equal to potential energy plus kinetic energy?
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
In a closed system energy is equal to potential energy plus kinetic energy.?
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
When is total mechanical energy conserved?
Total mechanical energy is conserved in a system when no external forces, such as friction or air resistance, are acting on the system. This often occurs in idealized situations like when an object is in free fall or when no energy is lost due to non-conservative forces.
Is momentum conserved in inelastic collision?
The energy of the momentum in a collision is conserved through the following occurrences; movement of vehicle(s) after impact, deformation of the vehicle(s) or objects hit, heat and sound.
Which physical quantity is conserved of an earth satellite?
The total mechanical energy of an Earth satellite (kinetic energy + potential energy) is conserved in the absence of non-conservative forces like air resistance or atmospheric drag. This means that as the satellite orbits Earth, its total energy remains constant.
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.
In a collision what is conserved?
In a collision, the total momentum of the system is conserved if no external forces act on the system. This means that the total momentum before the collision is equal to the total momentum after the collision.
What is conserved sum of potential and kinetic energy?
The total mechanical energy, which is the sum of potential and kinetic energy, is conserved in a closed system where only conservative forces are involved. This principle is known as the conservation of mechanical energy, which states that the total energy of a system remains constant if only internal forces (like gravitational or spring forces) are acting on it.
In situations is mechanical energy conserved?
Mechanical energy is conserved in situations where only conservative forces are present, such as gravity or spring forces. In these cases, the total mechanical energy (kinetic energy + potential energy) of a system remains constant as long as no external work is done.
When only mechanical energy acts on an object what is conserved?
When only mechanical energy acts on an object, the total mechanical energy of the system is conserved. This means that the sum of the object's kinetic and potential energies remains constant, assuming no external forces or sources of energy are involved.
Potential energy plus kinetic energy equal what?
The sum of potential energy and kinetic energy is equal to the total mechanical energy of a system. Mechanical energy = Potential energy + Kinetic energy.
When an object's total mechanical energy is NOT conserved?
When an object is subjected to external forces, such as friction or air resistance, its total mechanical energy is not conserved. Energy is converted into other forms, like heat or sound, causing a decrease in the object's mechanical energy. This results in a decrease in potential and kinetic energy as the object moves.
