1. Keep the refrigerator door closed as much as possible.
2. Don't watch television.
3. Turn lights off when you don't need them.
4. Cook food in microwave instead of oven.
5. Turn off computer.
By turning off lights or other devices you don't use and by installing energy-saving equipment (especially lights).
Energy can be conserved in daily activities by turning off lights and electronics when not in use, using energy-efficient appliances, insulating homes to reduce heating and cooling needs, and using public transportation or carpooling to reduce fuel consumption.
No. Total energy is always conserved, but not so mechanical energy.
no it's not cuz if there is friction energy wont be 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.
Not really, no.
Energy is always conserved in a closed system, according to the law of conservation of energy. However, in the universe as a whole, energy may not be conserved due to the expansion of space-time, which can lead to a net increase in energy.
In an inelastic collision, momentum is conserved. However, kinetic energy is not conserved as it is transferred to other forms such as heat, sound, or deformation energy.
Energy is conserved in a chemical reaction, meaning the total amount of energy before and after the reaction remains constant. This principle is known as the law of conservation of energy.
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.
Energy is always conserved. When friction is present, the energy usually just turns into heat.
biomass can be conserved by turning it into usable fuels
