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.
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.
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.
Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.
In a collision what is conserved?
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
Is mechanical energy always conserved Can you explain why or why not?
Mechanical energy is not always conserved. It can be converted into other forms of energy, such as heat or sound, through processes like friction or collisions. This means that the total amount of mechanical energy in a system may change over time, making it not always conserved.
What is conserved sum of potential and kinetic energy?
The sum of potential and kinetic energy is called "mechanical energy". This is NOT conserved, though - unless you consider the microscopic scale, in which case (for example) heat energy is a type of kinetic energy. In this case, the sum is simply the total energy, and the total energy IS conserved.
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?
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
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.
Mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved
