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.
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.
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.
Mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved
Is mechanical energy always conserved why or why not?
Mechanical energy is not always conserved. It can be converted into other forms of energy such as heat, sound, or work, due to external forces like friction or air resistance acting on the system. In the absence of non-conservative forces, mechanical energy is conserved according to the law of conservation of energy.
When you throw a matter from a height why mechanical energy is not conserved?
When you throw matter from a height, mechanical energy is not conserved by you, but it is by the matter. You are exerting mechanical energy to throw the object, and the matter is conserving it by not having to do any work to move.
Can an objects mechanical energy change?
Yes, it can. For instance, if you have friction in the system mechanical energy of the system is not conserved.
Which energy is always conserved?
Mechanical energy is always conserved in a closed system. It can exist as potential energy (stored energy) and kinetic energy (energy of motion). This conservation principle is known as the law of conservation of mechanical energy.
Is the mechanical energy always conserved?
No, mechanical energy is not always conserved. It can be transformed into other forms of energy, such as heat or sound, due to factors like friction or air resistance. However, in an idealized system without external forces, mechanical energy can be 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 mechanical energy is conserved as a playground swing moves?
Yes, mechanical energy is conserved as a playground swing moves. At the highest point of the swing, the potential energy is at its maximum, then as the swing moves downward, potential energy is converted to kinetic energy, and vice versa as it swings back up. Friction and air resistance cause small amounts of energy loss, but overall mechanical energy is conserved.
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.
