here, ill copy from my school :) lol. im learning this too. hope this helps :D
In a closed systemClosed System: A system where the total mass is a conserved quantity but the total energy is not., energy can enter or leave the system but matter cannot.
The planet Earth is an example of a closed system. The outer edge of the atmosphere acts as a boundary between the system, Earth, and its surroundings. Matter does not enter or leave the system, except for the occasional meteorite or shuttle, but energy is freely transferred between the Earth and its surroundings. Energy in the form of radiation from the Sun passes through the atmosphere to the Earth's surface. The Earth also emits radiation back out to space. Because energy passes across its atmosphere but matter usually does not, the Earth is considered a closed system.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
in closed systems
In a closed system, the total energy (kinetic + potential) remains constant, following the principle of conservation of energy. As kinetic energy increases, potential energy decreases, and vice versa. This continuous exchange between kinetic and potential energy allows the system to maintain a constant total energy.
1. A closed system is a system which is isolated so that it cannot exchange matter or energy with its surroundings.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
In a closed system, the total energy remains constant. When energy is added to a closed system, it can change form (e.g. from potential to kinetic energy) but the total amount of energy in the system remains the same.
In a closed system, neither the energy or matter changes. (Study Island)
No, in a closed system, matter and energy cannot enter or exit from the surroundings. The total amount of matter and energy remains constant within a closed system according to the law of conservation of mass and energy.
No, the roller coaster is not the only example of a closed energy system.
in closed systems
In a closed system, potential and kinetic energy can change but their total remains constant. This is known as the conservation of energy.
In a closed system, the rest of the energy not used for work or heat is typically converted into other forms of energy, such as sound, light, or stored as potential energy.
